I have progressed, I think.  _JBLEN was not being defined in
/usr/include/setjmp.h.  I don't know why, so I edited the file to
unconditionally set it to 6 since that looked like what it should be
set to based on all the ifdefs associated with that parameter.  I
don't know if this hurts me in some way but I am getting to a further
point.

When the make executes ./genflags md > tmp-flags.h, the following
occurs:


	./genflags md > tmp-flags.h
Expected character (.  Found character ^M.  At file position: -5
Following characters are:
	sh: 2939 Bus error - core dumped
*** Error code -118

Stop.

I've been experimenting and the read_skip_spaces in rtl.c doesn't seem
to be working properly.  I can't get genflags to do anything even with
the most trivial input.

Is this related to my hard coding _JBLEN equal to 6?  Is it a known
problem with SCO Unix Sys V R3.2.2?  To refresh, I use the rcc
compiler rather than the SCO cc compiler.
