Jeff, I'd like to get your input on this.

IMHO, it doesn't feel right to add __CYGWIN__ here since the %m
functionality is sufficiently target agnostic to be useful for everyone
who would like to use it.  I guess _GLIBC_EXTENSION sounds about right,
but maybe it should be _NO_GLIBC_EXTENSIONS instead and only set it
for builds which explicitely don't want them?
