AFAICT everyone who has tried has been successful in building and testing 
the standard gcc-3.4.1 and 3.4.2 on cygwin, but shows well over 100 
testsuite failures due to non-support of pch. At least 3 different people 
have posted the results on gcc-testsuite.  I don't count problems such as 
my failure to build it in 32-bit mode on x64.  C++ in my own current 
project doesn't build with 3.3.4, but is good with 3.4.x.  I agree that my 
project is not "important" nor trendy enough to backport fixes to 
3.3.x.  According to testsuite, Java is slightly better in 3.4.x.  I don't 
know that anyone has tackled the cygwin patches; inclusion of pch will no 
doubt make it much more time consuming.   I haven't seen anyone post 
testsuite results for that mingw 3.4.0 version, so your evidence that mingw 
is ahead of cygwin is lacking.
