 787 Usage: $0 [OPTION]... [VAR=VALUE]...
 788
 789 To assign environment variables (e.g., CC, CFLAGS...), specify them as
 790 VAR=VALUE.  See below for descriptions of some of the useful variables.
 791
 792 Defaults for the options are specified in brackets.
 793
 794 Configuration:
 795   -h, --help              display this help and exit
 796       --help=short        display options specific to this package
 797       --help=recursive    display the short help of all the included packages
 798   -V, --version           display version information and exit
 799   -q, --quiet, --silent   do not print \`checking...' messages
 800       --cache-file=FILE   cache test results in FILE [disabled]
 801   -C, --config-cache      alias for \`--cache-file=config.cache'
 802   -n, --no-create         do not create output files
 803       --srcdir=DIR        find the sources in DIR [configure dir or \`..']

 808 Installation directories:

 811   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
 812                           [PREFIX]
 813
 814 By default, \`make install' will install all the files in
 815 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
 816 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
 817 for instance \`--prefix=\$HOME'.
 818
 819 For better control, use the options below.

 844 Some influential environment variables:
 845   CC          C compiler command
 846   CFLAGS      C compiler flags
 847   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a

 849   CPPFLAGS    C/C++ preprocessor flags, e.g. -I<include dir> if you have

 852   CXXFLAGS    C++ compiler flags
 853   CPP         C preprocessor

5248    Here is a matrix of mmap possibilities:
5249         mmap private not fixed
5250         mmap private fixed at somewhere currently unmapped
5251         mmap private fixed at somewhere already mapped
5252         mmap shared not fixed
5253         mmap shared fixed at somewhere currently unmapped
5254         mmap shared fixed at somewhere already mapped
5255    For private mappings, we should verify that changes cannot be read()
5256    back from the file, nor mmap's back from the file at a different
5257    address.  (There have been systems where private was not correctly
5258    implemented like the infamous i386 svr4.0, and systems where the
5259    VM page cache was not coherent with the file system buffer cache
5260    like early versions of FreeBSD and possibly contemporary NetBSD.)
5261    For shared mappings, we should conversely verify that changes get
5262    propagated back to all the places they're supposed to be.
5263
5264    Grep wants private fixed already mapped.
5265    The main things grep needs to know about mmap are:
5266    * does it exist and is it safe to write into the mmap'd area
5267    * how to use it (BSD variants)  */
