make bootstrap croaks

[djh]

I just need some pointers so that I can look into some kind of building 
problem.

Platform: CYGWIN_NT-5.1 1.5.19(0.150/4/2)
Underlying OS: Japanese XP

configured:
./configure --prefix=$INSTALL_BASE_DIR --mandir=/usr/share/man 
--infodir=/usr/share/info --exec-prefix= --with-jpeg --with-png 
--with-gtk  --with-gif  --without-toolkit-scroll-bars --with-xpm 
--with-tiff  --x-includes=/usr/X11R6/include/X11 
--x-libraries=/usr/X11R6/lib

$ make boostrap

make[2]: *** [bootstrap-emacs.exe] Segmentation fault (core dumped)
make[2]: Leaving directory `/cygdrive/c/emacs/cvs/emacs/src'
make[1]: *** [bootstrap-build] Error 2

How do I attach a gdb to this?  
Once into the debugger I can trace to see the cause.
Or is there an even more elequent way?

Thanks,
