I thought there were some patches to the cygwin gcc 3.4.x version that 
had not yet been migrated to the official sources?  I'd be glad to be 
wrong, however.

Also, wasn't there some issue with the std::string implementation that 
was causing problems for both cygwin-special and mingw-special g++? 
Otherwise, if it's so simple, I don't understand why Gerrit hasn't 
released gcc-4.x as a test version, nor [OT:] why Danny hasn't released 
a gcc-4.0 candidate for mingw.

Other than "we're just mean". :-)

I mean, hey, they're volunteers and far be it from me to criticize, 
given my lackluster record as a maintainer of late...but somehow I doubt 
that it's really as easy as you claim -- otherwise those two guys woulda 
done it by now.
