* acinclude.m4
* m4macros/Makefile.am
* m4macros/detectcflags.m4: new macro: GIMP_DETECT_CFLAGS; used
to detect which of a set of compiler options a compiler supports.
* configure.in: use the above for the altivec and -fno-strict-aliasing
flags. Also, use it to detect the presence of -mmmx and -msse, since
those are needed to compile even MMX/SSE assembly with gcc 4.0. Define
MMX/SSE_EXTRA_CFLAGS.
* app/composite/Makefile.am: compile each of the composite flavors
into their own library, so we can use automake's per-target CFLAGS.
Use MMX/SSE/ALTIVEC_EXTRA_CFLAGS in the appropriate places. Build
libappcomposite.a out of the resulting objects.
* app/composite/gimp-composite-3dnow.c
* app/composite/gimp-composite-altivec.c
* app/composite/gimp-composite-mmx.c
* app/composite/gimp-composite-sse.c
* app/composite/gimp-composite-sse2.c
* app/composite/gimp-composite-vis.c
* app/composite/make-installer.py: move the _init functions into
the installers, so only actually mmx/sse/etc. code gets compiled
under the appropriate CFLAGS.
* app/composite/gimp-composite-3dnow-installer.c
* app/composite/gimp-composite-altivec-installer.c
* app/composite/gimp-composite-mmx-installer.c
* app/composite/gimp-composite-sse-installer.c
* app/composite/gimp-composite-sse2-installer.c
* app/composite/gimp-composite-vis-installer.c: regenerated.
* app/composite/gimp-composite.c: remove useless cpu-accel.h include.
