I removed the -msoft-float but am still getting the same crash problem.  I 
must be adding or missing another switch.  I am using the crt0.o and libc.a 
that comes with the uClinux-distribution-20010622.tar.gz which is different 
than the one that comes with the m68k-elf-tools-20010716.tar.gz.  I assume I 
am to use the one that comes with the uClinux-distribution since that is the 
one that the userland apps use in the uClinux-distribution and they work.
