Please be explicit as to whether you're using Cygwin or not. Also, what
exactly do you mean by "extra GNU features"? Cygwin doesn't use GNU C
library, so the issue is moot as far as library features go.

What regexp? GNU C library and Mingw32 are not related in any way, so 
unless you're talking about ANSI/ISO features, you can't expect it to
match up.

It's just a convention, without any consequence; just ignore it. If you
want to produce code for 686, then see the GCC manual on what switches
you need to provide (specifically look at the -mcpu and -march options).
