cygwin support being dropped as of gcc-4.1?

[Tim Prince]

As cygwin g++ build has not been supported for a long time in the 4.1 
branch, and I've heard rumors there is no intention of doing so,  I have 
some concern about working on cygwin.  I doubt there will ever be a 
cygwin release without g++ support. 
gcj has dropped support for splitting link commands to fit the command 
buffer limit, and doing the same with gfortran would prevent it also 
from running on cygwin.
I suppose the 4.0.2 branch is unlikely to accept performance patches. 
Relevance of cygwin will decrease, if there is no enabling of 64-bit 
build mode, so I suppose someone may think it is not worth the effort to 
support it.
