No problem with gcc3. BUT on OSX 10.4 the warning (with caution it will be
fatal eventually):

bsad.c: In function 'bsad_altivec':
bsad.c:160: warning: target of assignment not really an lvalue; this will be a hard error in the future

on Fedora Core4 Test3 it's a fatal error.

Fix is to cast the return value to the variable type. Intead of

vu8(fH) = vec_mergeh(zero, vf);

use something like:

fH = vu16(vec_mergeh(zero, vf));

Sigh - have to use vs8 instead of vu8 to placate gcc3 and 4 at the same time.

check if -maltivec is accepted and if so add it to ALTIVEC_CFLAGS. Later
versions of gcc (gcc4) won't generate vectorized memset/memcpy unless both
-faltivec and -maltivec are given.

Use strcasecmp instead of strcmp to shorten the extension checking.
