Many older +dnl installations will not provide this file, but some will have the +dnl very same definitions in <inttypes.h>. In other enviroments we can +dnl use the inet-types in <sys/types.h> which would define the typedefs +dnl int8_t and u_int8_t respectivly. +dnl +dnl This macros will create a local "_stdint.h" or the headerfile given +dnl as an argument. In many cases that file will just "#include +dnl <stdint.h>" or "#include <inttypes.h>", while in other environments +dnl it will provide the set of basic 'stdint's definitions/typedefs: +dnl +dnl int8_t,uint8_t,int16_t,uint16_t,int32_t,uint32_t,intptr_t,uintptr_t +dnl int_least32_t.. int_fast32_t.. intmax_t +dnl +dnl which may or may not rely on the definitions of other files, or +dnl using the AC_CHECK_SIZEOF macro to determine the actual sizeof each +dnl type. +dnl +dnl if your header files require the stdint-types you will want to +dnl create an installable file mylib-int.h that all your other +dnl installable header may include. So if you have a library package +dnl named "mylib", just use +dnl +dnl AX_CREATE_STDINT_H(mylib-int.h) +dnl +dnl in configure.ac and go to install that very header file in +dnl Makefile.am along with the other headers (mylib.h) - and the +dnl mylib-specific headers can simply use "#include <mylib-int.h>" to +dnl obtain the stdint-types. +dnl +dnl Remember, if the system already had a valid <stdint.h>, the +dnl generated file will include it directly.

It +# sets the PTHREAD_LIBS output variable to the threads library and linker +# flags, and the PTHREAD_CFLAGS output variable to any special C compiler +# flags that are needed. (The user can also force certain compiler +# flags/libs to be tested by setting these environment variables.) +# +# Also sets PTHREAD_CC to any special C compiler that is needed for +# multi-threaded programs (defaults to the value of CC otherwise). (This +# is necessary on AIX to use the special cc_r compiler alias.) +# +# NOTE: You are assumed to not only compile your program with these flags, +# but also to link with them as well. For example, you might link with +# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS +# +# If you are only building threaded programs, you may wish to use these +# variables in your default LIBS, CFLAGS, and CC: +# +# LIBS="$PTHREAD_LIBS $LIBS" +# CFLAGS="$CFLAGS $PTHREAD_CFLAGS" +# CC="$PTHREAD_CC" +# +# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant +# has a nonstandard name, this macro defines PTHREAD_CREATE_JOINABLE to +# that name (e.g. PTHREAD_CREATE_UNDETACHED on AIX). +# +# Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the +# PTHREAD_PRIO_INHERIT symbol is defined when compiling with +# PTHREAD_CFLAGS. +# +# ACTION-IF-FOUND is a list of shell commands to run if a threads library +# is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it +# is not found. If ACTION-IF-FOUND is not specified, the default action +# will define HAVE_PTHREAD. +# +# Please let the authors know if this macro fails on any platform, or if +# you have any other suggestions or comments. This macro was based on work +# by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help +# from M. Frigo), as well as ac_pthread and hb_pthread macros posted by +# Alejandro Forero Cuervo to the autoconf macro repository.
