This means that a configure operation as innocuous-looking as
CFLAGS="-O3" ./configure
will break the build on gcc >= 3.3 because it will fail to supply -fno-strict-aliasing. I claim this is a lousy idea. We should drop the if-test and always add -fno-strict-aliasing if the compiler will take it. People who *really* know what they are doing can experiment with removing the switch from Makefile.global after configure, but I don't think it should be quite this easy to lose it.
I agree.
