1414 CC C compiler command
1415 CFLAGS C compiler flags
1416 LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
1417 nonstandard directory <lib dir>
81ecdfbb 1418 LIBS libraries to pass to the linker, e.g. -l<library>
d0ac1c44 1419 CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
81ecdfbb 1420 you have headers in a nonstandard directory <include dir>

PA		 1421 CXX C++ compiler command
1422 CXXFLAGS C++ compiler flags
bec39cab
AC		 1423 CPP C preprocessor

1425Use these variables to override the choices made by `configure' or to help
1426it to find libraries and programs with nonstandard names/locations.

7143 Here is a matrix of mmap possibilities:
7144 mmap private not fixed
7145 mmap private fixed at somewhere currently unmapped
7146 mmap private fixed at somewhere already mapped
7147 mmap shared not fixed
7148 mmap shared fixed at somewhere currently unmapped
7149 mmap shared fixed at somewhere already mapped
7150 For private mappings, we should verify that changes cannot be read()
7151 back from the file, nor mmap's back from the file at a different
7152 address. (There have been systems where private was not correctly
7153 implemented like the infamous i386 svr4.0, and systems where the
7154 VM page cache was not coherent with the file system buffer cache
7155 like early versions of FreeBSD and possibly contemporary NetBSD.)
7156 For shared mappings, we should conversely verify that changes get
7157 propagated back to all the places they're supposed to be.
7158
7159 Grep wants private fixed already mapped.
7160 The main things grep needs to know about mmap are:
7161 * does it exist and is it safe to write into the mmap'd area
7162 * how to use it (BSD variants) */
