Actually, -mno-cygwin has been part of standard gcc for some time. The
cygwin version of gcc does have some additional patches which make things
more robust but for gcc 3.4, these changes are all part of the base.
So, the bottom line is that -mno-cygwin should more or less work in
most versions of gcc.
