that comparison isn't quite fair. strict aliasing is an optimisation that
breaks code when compiled with a newer version of gcc, and there is lots of
code to fix because of that.
Sure, you can fix it by reading th

background: glibc 2.3 CVS attributes "fwrite" and "write" with it, and it
causes a lot (in the hundreds/thousands) of false positives for bigger software
projects, because while it is indeed the case

Care to explain how it is a glibc bug? its not documented that there shouldn't
be a way to suppress the warning.
I agree glibc is overly paranoid and pedantic, but that doesn't make it less of
a gcc issue.

yes, well one reason for it is that several libs (e.g. libgcc2) already use
