2020 Installation directories:
2021   --prefix=PREFIX         install architecture-independent files in PREFIX
2022                           [$ac_default_prefix]

2024                           [PREFIX]
2025
2026 By default, \`make install' will install all the files in
2027 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
2028 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
2029 for instance \`--prefix=\$HOME'.

10084    Here is a matrix of mmap possibilities:
10085         mmap private not fixed
10086         mmap private fixed at somewhere currently unmapped
10087         mmap private fixed at somewhere already mapped
10088         mmap shared not fixed
10089         mmap shared fixed at somewhere currently unmapped
10090         mmap shared fixed at somewhere already mapped
10091    For private mappings, we should verify that changes cannot be read()
10092    back from the file, nor mmap's back from the file at a different
10093    address.  (There have been systems where private was not correctly
10094    implemented like the infamous i386 svr4.0, and systems where the
10095    VM page cache was not coherent with the file system buffer cache
10096    like early versions of FreeBSD and possibly contemporary NetBSD.)
10097    For shared mappings, we should conversely verify that changes get
10098    propagated back to all the places they're supposed to be.
10099
10100    Grep wants private fixed already mapped.
10101    The main things grep needs to know about mmap are:
10102    * does it exist and is it safe to write into the mmap'd area
10103    * how to use it (BSD variants)  */
