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.
