I broke down in a similar place.  This is after the compiler has
bootstrapped.   Line 178 in mknumeric_limits is the area where
that script tries to compile gen-num-limits but I wasn't able to root
cause it.  I ran the compile that dumped core by hand and it worked
fine.  Running 'gmake bootstrap' again got the build to continue
on its way (it is still building - takes over 14 hours for this
build to complete on this machine/os).
