Successful build of CVS GCC under Cygwin!

[Jan Reimers]

Kelly,         Thanks for 
the update, this is useful information.  I followed your directions and 
'make bootstrap' seemed to run ok.  However when I run 'make -k check' all 
c++ tests fail with undefined references.  Is this what you 
see? libtool: link: warning: `-no-install' is ignored for
