[MPlayer-dev-eng] configure is duplicating some CFLAGS

[Rowan James]

I'm not yet sure how recent this is - I need to clean up a bit before I can bisect properly if needed; am desperately low on drive space ^_^

This was at least not produced when I submitted the patch for r31910, as clang would have been giving warnings for the ignored duplicate (as shown below) - there's a big chunk of $CFLAGS being duplicated in the CC args.


On Darwin x86_64 w/ gcc 4.2.1 (Apple)

$configure && make

cc -MD -MP -O4 -march=core2 -mtune=core2 -pipe -ffast-math -fomit-frame-pointer -Wundef -Wall -Wno-switch -Wno-parentheses -Wpointer-arith -Wredundant-decls -Wstrict-prototypes -Wmissing-prototypes -Wdisabled-optimization -Wno-pointer-sign -Wdeclaration-after-statement -std=gnu99  -O4 -march=core2 -mtune=core2 -pipe -ffast-math -fomit-frame-pointer -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -D_LARGEFILE64_SOURCE -Ilibdvdread4 -falign-loops=16 -shared-libgcc -mdynamic-no-pic -I. -Iffmpeg  -DPIC  -I/usr/X11/include -I/usr/X11/include/freetype2 -I/usr/X11/include -c -o command.o command.c

where we see duplicated:
-O4 -march=core2 -mtune=core2 -pipe -ffast-math -fomit-frame-pointer

Or with recent SVN clang (same platform)

$ configure --cc=/Users/rowanj/clang/bin/clang && make

/Users/rowanj/clang/bin/clang -MD -MP -D_ISOC99_SOURCE -D_BSD_SOURCE -O2 -march=core2 -pipe -D_ISOC99_SOURCE -D_BSD_SOURCE -O2 -march=core2 -pipe -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -D_LARGEFILE64_SOURCE -Ilibdvdread4 -mdynamic-no-pic -I. -Iffmpeg  -DPIC  -I/usr/X11/include -I/usr/X11/include/freetype2 -I/usr/X11/include -c -o libmpdemux/ebml.o libmpdemux/ebml.c
