If you aren't a linux kernel maintainer (and heavens knows there are
plenty of other programs compiled with gcc, even if the linux kernel
folks fail to realize that), you care about portability.

Personally, I love being warned that what I've written might behave
differently on 64-bit pointer environments, or other compilers, or
... whatever.

Let's add a new flag for linux:

Today I was writing a parser that rewrites C programs to guarantee
certain important properties (among them, security!). It works
wonderfully on many OSs. It does not work on Linux. Why? Because
the Linux headers are absolutely riddled with completely unnecessary
uses of gcc extensions.

I really hate how Linux kernel and libc maintainers insist on
"embracing and extending" the ISO C standard.
