I thought it was only necessary to define UNICODE. _UNICODE seems like it ought to be a compiler-internals sort of thing.

Does using g++ instead of gcc for both stages help any? cheers, DaveK -- Can't think of a witty .sigline today.... -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
