Successful build of GCC 4.2.0 RC3 on latest Cygwin snapshot 20070427

[Aaron Gray]

I have successfully built GCC-4.2.0-20070501 on latest Cygwin snapshot 
20070427.

GCC 4.2.0 RC3 is available from:
       ftp://gcc.gnu.org/pub/gcc/prerelease-4.2.0-20070501

I have not done run the testsuite ( make check) but have built LLVM and 
LLVM-GCC4. So indications are very good.
