acinclude.m4 (GLIBCXX_EXPORT_INCLUDES): Remove LIBMATH_INCLUDES and LIBSUPCXX_INCLUDES.
2003-08-17 Phil Edwards <pme@gcc.gnu.org> * acinclude.m4 (GLIBCXX_EXPORT_INCLUDES): Remove LIBMATH_INCLUDES and LIBSUPCXX_INCLUDES. Re-purpose TOPLEVEL_INCLUDES to refer to things from the top level. * configure.ac (GLIBCXX_IS_NATIVE): Determine earlier and re-order. Comment out the conditionals for CANADIAN and GLIBCXX_BUILD_LIBMATH (currently unused). Strip the fake-VPATH shell fragment from automake-generated rules, if present. * linkage.m4: Add comment. * fragment.am: New file, containing factored-out common settings. (AM_CPPFLAGS): Absorb the deprecated INCLUDES variable contents. * Makefile.am: Include fragment.am. Remove common variables. * include/Makefile.am: Likewise. * libmath/Makefile.am: Likewise. * libsupc++/Makefile.am: Likewise. * po/Makefile.am: Likewise. Print rules during check. * src/Makefile.am: Likewise. * testsuite/Makefile.am: Likewise. * aclocal.m4, configure, Makefile.in, include/Makefile.in, libmath/Makefile.in, libsupc++/Makefile.in, po/Makefile.in, src/Makefile.in, testsuite/Makefile.in: Regenerate.

+ 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()

+ 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.
+ The main things grep needs to know about mmap are:
+ * does it exist and is it safe to write into the mmap'd area
+ * how to use it (BSD variants) */

- 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.
