1332 \`configure' configures gdbsupport 1.0 to adapt to many kinds of systems.
1333
1334 Usage: $0 [OPTION]... [VAR=VALUE]...
1335
1336 To assign environment variables (e.g., CC, CFLAGS...), specify them as
1337 VAR=VALUE.  See below for descriptions of some of the useful variables.
1338
1339 Defaults for the options are specified in brackets.
1340
1341 Configuration:
1342   -h, --help              display this help and exit
1343       --help=short        display options specific to this package
1344       --help=recursive    display the short help of all the included packages
1345   -V, --version           display version information and exit
1346   -q, --quiet, --silent   do not print \`checking ...' messages
1347       --cache-file=FILE   cache test results in FILE [disabled]
1348   -C, --config-cache      alias for \`--cache-file=config.cache'
1349   -n, --no-create         do not create output files
1350       --srcdir=DIR        find the sources in DIR [configure dir or \`..']
1351
1352 Installation directories:
1353   --prefix=PREFIX         install architecture-independent files in PREFIX
1354                           [$ac_default_prefix]
1355   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
1356                           [PREFIX]
1357
1358 By default, \`make install' will install all the files in
1359 \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
1360 an installation prefix other than \`$ac_default_prefix' using \`--prefix',
1361 for instance \`--prefix=\$HOME'.
1362
1363 For better control, use the options below.

1365 Fine tuning of the installation directories:
1366   --bindir=DIR            user executables [EPREFIX/bin]
1367   --sbindir=DIR           system admin executables [EPREFIX/sbin]

1440 Some influential environment variables:
1441   CC          C compiler command
1442   CFLAGS      C compiler flags
1443   LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
1444               nonstandard directory <lib dir>
1445   LIBS        libraries to pass to the linker, e.g. -l<library>
1446   CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
1447               you have headers in a nonstandard directory <include dir>
1448   CXX         C++ compiler command
1449   CXXFLAGS    C++ compiler flags
1450   CPP         C preprocessor
1451
1452 Use these variables to override the choices made by `configure' or to help
1453 it to find libraries and programs with nonstandard names/locations.

8490    Here is a matrix of mmap possibilities:
8491         mmap private not fixed
8492         mmap private fixed at somewhere currently unmapped
8493         mmap private fixed at somewhere already mapped
8494         mmap shared not fixed
8495         mmap shared fixed at somewhere currently unmapped
8496         mmap shared fixed at somewhere already mapped
8497    For private mappings, we should verify that changes cannot be read()
8498    back from the file, nor mmap's back from the file at a different
8499    address.  (There have been systems where private was not correctly
8500    implemented like the infamous i386 svr4.0, and systems where the
8501    VM page cache was not coherent with the file system buffer cache
8502    like early versions of FreeBSD and possibly contemporary NetBSD.)
8503    For shared mappings, we should conversely verify that changes get
8504    propagated back to all the places they're supposed to be.
8505
8506    Grep wants private fixed already mapped.
8507    The main things grep needs to know about mmap are:
8508    * does it exist and is it safe to write into the mmap'd area
8509    * how to use it (BSD variants)  */
