OK, what gcc versions support -fno-strict-aliasing? Do we need a
configure test for it?
Perhaps ... although it is recognized in 2.95.3 and probably for a good ways before that.
It looks to me like what has changed in gcc 3.3 is not the existence of the flag, but the fact that -O2 now turns it on where it did not before.
Yes, exactly - I have just confirmed this on the archived manuals on the gcc site.
But turning it off for earlier releases does no harm.
It is known to break 2.7.1 and I believe it will work with 2.95 and later.
