Description ferret 2004-02-10 13:32:40 UTC

I'm attaching some output. Note, I realise the subject of this bug isn't the
reason for the compilation failure; the reason is some-other-bug, but never mind
that. The amount of warnings here is ridiculous! My CFLAGS:

CFLAGS="-march=athlon-xp -O2 -pipe -fomit-frame-pointer -fprefetch-loop-arrays
-mfpmath=387,sse"

However, I tried with CFLAGS="-O2" and the warnings still occurred. With
CFLAGS="-O", it doesn't. Are these non-fatal warnings "worth" a stripping of the
CFLAGS?

not really important. -O2 activates -fstrict-aliasing which produces those warnings. it is the way the bindings are structure that produce the warnings. they won't do anything bad. you can check the gcc info page for more information.
