WJFFM.  <http://gcc.gnu.org/ml/gcc-testresults/2006-05/msg01102.html>  I
have never experienced either of the issues you mentioned.  The
"successful reports" thing is completely bogus.  Just look in the
testresults archive, you'll see plenty of people build and test gcc 4
under Cygwin regularly.

--enable-__cxa-atexit is definitely incorrect.  That's only for C
libraries that support it, such as glibc.  Cygwin is certainly not one. 
I also would not bother with profiledbootstrap, it would not surprise me
at all to hear that it is broken on non-primary targets.
