'check' searches for such packages, and behaves as if 'yes' or 'no' were given, accordingly. 'yes' generates compatibility wrappers for the vendor-provided packages to allow their use with groff and related tools. The compatibility wrappers are installed using the vendor-provided names, while their groff implementations are installed with a 'g' prefix. Use of the latter thus requires options of the form '-mg' (example: -mgan). 'no' installs only the groff implementations. 'manual' generates compatibility wrappers for the vendor-provided packages as '-os'. Use of the latter thus requires options of the form '-m-os' option (example: -man-os). --with-alt-gs=LIST alternative names for ghostscript executable --with-gs=PROG actual [/path/]name of ghostscript executable --with-alt-awk=LIST alternative names for awk executable --with-awk=PROG actual [/path/]name of awk executable Some influential environment variables: CC C compiler command CFLAGS C compiler flags LDFLAGS linker flags, e.g. -L if you have libraries in a nonstandard directory LIBS libraries to pass to the linker, e.g. -l CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I if you have headers in a nonstandard directory CXX C++ compiler command CXXFLAGS C++ compiler flags CPP C preprocessor XMKMF Path to xmkmf, Makefile generator for X Window System PKG_CONFIG path to pkg-config utility PKG_CONFIG_PATH directories to add to pkg-config's search path PKG_CONFIG_LIBDIR path overriding pkg-config's built-in search path UCHARDET_CFLAGS C compiler flags for UCHARDET, overriding pkg-config UCHARDET_LIBS linker flags for UCHARDET, overriding pkg-config CXXCPP C++ preprocessor Use these variables to override the choices made by `configure' or to help it to find libraries and programs with nonstandard names/locations.

Here is a matrix of mmap possibilities: mmap private not fixed mmap private fixed at somewhere currently unmapped mmap private fixed at somewhere already mapped mmap shared not fixed mmap shared fixed at somewhere currently unmapped mmap shared fixed at somewhere already mapped For private mappings, we should verify that changes cannot be read() back from the file, nor mmap's back from the file at a different address. (There have been systems where private was not correctly implemented like the infamous i386 svr4.0, and systems where the VM page cache was not coherent with the file system buffer cache like early versions of FreeBSD and possibly contemporary NetBSD.) For shared mappings, we should conversely verify that changes get propagated back to all the places they're supposed to be. Grep wants private fixed already mapped.
