build failure of 21.4.8 with latest gcc-3.1.1-4 under cygwin

Hi I just tried rebuilding xemacs-21.4.8 (which builds perfectly under gcc-2.95.3-9) under gcc-3.1.1-4 / cygwin-1.3.12-4 and got the following errors leaving behind an emacs.exe with 0 bytes. Any hints ?? Loading site-load... Finding pointers to doc strings...
