Subject: [PATCH] re PR ada/6852 (gnatlib fails to build with newlib because it
 doesn't set up the include path)

2005-03-08  Doug Rupp  <rupp@adacore.com>
	    Bernard Banner  <banner@adacore.com>
	    Vincent Celier  <celier@adacore.com>
	    Arnaud Charlet  <charlet@adacore.com>

	PR ada/6852
	This change works fine when gnatlib is built from the gcc directory,
	but does not work when using the libada Makefile, since GCC_FOR_TARGET
	is not passed to ada/Makefile.in, so more work is needed by a
	Makefile/configure expert.

	* Makefile.in(gnatlib): Use $(GCC_FOR_TARGET) for compiling library.
	set GMEM_LIB on ia64 linux to add optional support for gnatmem.
	Setup gnatlink switch -M for x86_64 linux, as it is already setup
	for Linux x86.
	(gnatlib-shared-default): Use GNATLIBCFLAGS as well.
	Run ranlib on libgccprefix.a
	Define PREFIX_OBJS for Darwin, to build libgccprefix.
	(ADA_INCLUDE_SRCS): Split Ada packages.
