Specifying CC/CFLAGS on the commandline doesn't work:

Invader:cc65-snapshot-2.12.9.20090925 pelle$ make CC=clang CFLAGS=-O4
-f make/gcc.mak
for i in common ar65 ca65 cc65 cl65 co65 da65 grc ld65 od65; do make
-C $i -f make/gcc.mak all || exit $?; done
Creating dependency information
gcc -g -O2 -Wall -W -std=c89 -MM abend.c addrsize.c bitops.c
chartype.c check.c cmdline.c coll.c cpu.c debugflag.c exprdefs.c
filepos.c filetype.c fname.c fp.c hashstr.c hashtab.c intstack.c

strbuf.c strpool.c strstack.c strutil.c target.c tgttrans.c xmalloc.c
xsprintf.c > .depend
gcc -g -O2 -Wall -W -std=c89   -c -o abend.o abend.c
gcc -g -O2 -Wall -W -std=c89   -c -o addrsize.o addrsize.c
gcc -g -O2 -Wall -W -std=c89   -c -o bitops.o bitops.c
...etc

The variables aren't inherited when make is called again inside the
makefile. Setting MAKE like so:

MAKE=make CC=clang CFLAGS=-O4

in the makefile works, however (yay!).

PS: building with clang doesn't work though. llvm-gcc-4.2 (4.0) also
fails, but looks a little better...
