Okay so I rebuilt Wine with _FORTIFY_SOURCE=0 in my CFLAGS and that worked. But
according to features.h, 0 should be the default. So I did a little more
digging and found this in Gentoo GCC patches.

"NOTE: In Gentoo, @option{-D_FORTIFY_SOURCE=2} is set by default, and is
activated when @option{-O} is set to 2 or higher.  This enables additional
compile-time and run-time checks for several libc functions.  To disable,
specify either @option{-U_FORTIFY_SOURCE} or @option{-D_FORTIFY_SOURCE=0}."

Aha! Now I could go pester the Gentoo Wine maintainers but if you know that
this option breaks Wine then maybe Wine should force it to 0? That's my opinion
but I'll leave it up to you.
