IMO, yes.  They are not exactly the same but they should be very
very close.

It is a sticky problem because we don't include a mingw C++ library
(despite my frequent begging) in cygwin, so some errors that people will
experience are actually cygwin specific and shouldn't pollute the
mingw mailing list.

However, the specific problem that this person was not due to anything
like this.  It was a pure windows problem, as far as I could tell.

So, probably the FAQ should suggest that -mno-cygwin uses a
subset of the functionality found at www.mingw.org.  Before people
report problems with -mno-cygwin they should 1) check the cygwin
mailing list archives and 2) check the mingw web site.  Also, adding
words about the libstdc++.a library might help.
