I'm confused on the logic of this whole series of tests.
I don't understand the syntax of the egrep line or the expected output
of /lib/cpp, but it looks like it's searching for instances of "ulong" in the
output of the preprocessor.
If it finds them, it sets ac_cv_type_ulong=yes. Persumably, this means
ulong cannot be found in the includes because cpp is complaining. It seems
like one should now do test #2 since there may still be a compiler built-in.
Problem is, test #2 is only performed when ac_cv_type_ulong=no.
Do I have it backwards?

sys/bsd_types uses typedefs:
typedef unsigned long ulong;

Yes, this compile works (once I edited uint and ushort out of confdefs.h).
