+
+ Suppress extern inline with HP-UX cc, as it appears to be broken; see
+ <https://lists.gnu.org/r/bug-texinfo/2013-02/msg00030.html>.
+
+ Suppress extern inline with Sun C in standards-conformance mode, as it
+ mishandles inline functions that call each other. E.g., for 'inline void f
+ (void) { } inline void g (void) { f (); }', c99 incorrectly complains
+ 'reference to static identifier "f" in extern inline function'.
+ This bug was observed with Sun C 5.12 SunOS_i386 2011/11/16.
+
+ Suppress extern inline (with or without __attribute__ ((__gnu_inline__)))
+ on configurations that mistakenly use 'static inline' to implement
+ functions or macros in standard C headers like <ctype.h>. For example,
+ if isdigit is mistakenly implemented via a static inline function,
+ a program containing an extern inline function that calls isdigit
+ may not work since the C standard prohibits extern inline functions
+ from calling static functions (ISO C 99 section 6.7.4.(3).
+ This bug is known to occur on:
+
+ OS X 10.8 and earlier; see:
+ https://lists.gnu.org/r/bug-gnulib/2012-12/msg00023.html
+
+ DragonFly; see
+ http://muscles.dragonflybsd.org/bulk/bleeding-edge-potential/latest-per-pkg/ah-tty-0.3.12.log
+
+ FreeBSD; see:
+ https://lists.gnu.org/r/bug-gnulib/2014-07/msg00104.html
+
+ OS X 10.9 has a macro __header_inline indicating the bug is fixed for C and
+ for clang but remains for g++; see <https://trac.macports.org/ticket/41033>.
+ Assume DragonFly and FreeBSD will be similar.
+
+ GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
+ inline semantics, unless -fgnu89-inline is used. It defines a macro
+ __GNUC_STDC_INLINE__ to indicate this situation or a macro
+ __GNUC_GNU_INLINE__ to indicate the opposite situation.
+ GCC 4.2 with -std=c99 or -std=gnu99 implements the GNU C inline
+ semantics but warns, unless -fgnu89-inline is used:
+ warning: C99 inline functions are not supported; using GNU89
+ warning: to disable this warning use -fgnu89-inline or the gnu_inline function attribute
+ It defines a macro __GNUC_GNU_INLINE__ to indicate this situation.

+dnl functionality.

+
+dnl Macro to add for using GNU gettext.
+
+dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
+dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
+dnl default (if it is not specified or empty) is 'no-libtool'.
+dnl INTLSYMBOL should be 'external' for packages with no intl directory,
+dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory.
+dnl If INTLSYMBOL is 'use-libtool', then a libtool library
+dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static,
+dnl depending on --{enable,disable}-{shared,static} and on the presence of
+dnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
+dnl $(top_builddir)/intl/libintl.a will be created.
+dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
+dnl implementations (in libc or libintl) without the ngettext() function
+dnl will be ignored. If NEEDSYMBOL is specified and is
+dnl 'need-formatstring-macros', then GNU gettext implementations that don't
+dnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
+dnl INTLDIR is used to find the intl libraries. If empty,
+dnl the value '$(top_builddir)/intl/' is used.
+dnl
+dnl The result of the configuration is one of three cases:
+dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
+dnl and used.
+dnl Catalog format: GNU --> install in $(datadir)
+dnl Catalog extension: .mo after installation, .gmo in source tree
+dnl 2) GNU gettext has been found in the system's C library.
+dnl Catalog format: GNU --> install in $(datadir)
+dnl Catalog extension: .mo after installation, .gmo in source tree
+dnl 3) No internationalization, always use English msgid.
+dnl Catalog format: none
+dnl Catalog extension: none
+dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
+dnl The use of .gmo is historical (it was needed to avoid overwriting the
+dnl GNU format catalogs when building on a platform with an X/Open gettext),
+dnl but we keep it in order not to force irrelevant filename changes on the
+dnl maintainers.

+dnl Sets the HOST_CPU variable to the canonical name of the CPU.
+dnl Sets the HOST_CPU_C_ABI variable to the canonical name of the CPU with its
+dnl C language ABI (application binary interface).
+dnl Also defines __${HOST_CPU}__ and __${HOST_CPU_C_ABI}__ as C macros in
+dnl config.h.
+dnl
+dnl This canonical name can be used to select a particular assembly language
+dnl source file that will interoperate with C code on the given host.
+dnl
+dnl For example:
+dnl * 'i386' and 'sparc' are different canonical names, because code for i386
+dnl will not run on SPARC CPUs and vice versa. They have different
+dnl instruction sets.
+dnl * 'sparc' and 'sparc64' are different canonical names, because code for
+dnl 'sparc' and code for 'sparc64' cannot be linked together: 'sparc' code
+dnl contains 32-bit instructions, whereas 'sparc64' code contains 64-bit
+dnl instructions. A process on a SPARC CPU can be in 32-bit mode or in 64-bit
+dnl mode, but not both.
+dnl * 'mips' and 'mipsn32' are different canonical names, because they use
+dnl different argument passing and return conventions for C functions, and
+dnl although the instruction set of 'mips' is a large subset of the
+dnl instruction set of 'mipsn32'.
+dnl * 'mipsn32' and 'mips64' are different canonical names, because they use
+dnl different sizes for the C types like 'int' and 'void *', and although
+dnl the instruction sets of 'mipsn32' and 'mips64' are the same.
+dnl * The same canonical name is used for different endiannesses. You can
+dnl determine the endianness through preprocessor symbols:
+dnl - 'arm': test __ARMEL__.
+dnl - 'mips', 'mipsn32', 'mips64': test _MIPSEB vs. _MIPSEL.
+dnl - 'powerpc64': test _BIG_ENDIAN vs. _LITTLE_ENDIAN.
+dnl * The same name 'i386' is used for CPUs of type i386, i486, i586
+dnl (Pentium), AMD K7, Pentium II, Pentium IV, etc., because
+dnl - Instructions that do not exist on all of these CPUs (cmpxchg,
+dnl MMX, SSE, SSE2, 3DNow! etc.) are not frequently used. If your
+dnl assembly language source files use such instructions, you will
+dnl need to make the distinction.
+dnl - Speed of execution of the common instruction set is reasonable across
+dnl the entire family of CPUs. If you have assembly language source files
+dnl that are optimized for particular CPU types (like GNU gmp has), you
+dnl will need to make the distinction.

+dnl by Intel Corporation.
+
+dnl Test whether in a situation where
+dnl - an rwlock is taken by a reader and has a writer waiting,
+dnl - an additional reader requests the lock,
+dnl - the waiting writer and the requesting reader threads have the same
+dnl priority,
+dnl the requesting reader thread gets blocked, so that at some point the
+dnl waiting writer can acquire the lock.
+dnl Without such a guarantee, when there a N readers and each of the readers
+dnl spends more than 1/Nth of the time with the lock held, there is a high
+dnl probability that the waiting writer will not get the lock in a given finite
+dnl time, a phenomenon called "writer starvation".
+dnl Without such a guarantee, applications have a hard time avoiding writer
+dnl starvation.
+dnl
