This problem is now fixed. I didn't make any changes to the source
codes. The only change I made is to  re-compile regex.c with -Oa
OFF (i.e. -Oilt -Gs instead of -Ox) and link the program again.
The program also works when I compile the whole program in small
model (the version I am using). So I assume there is at least a
optimization bug in MSC 5.1 but I don't have time to track down
the problem.

The fixes to the other two bugs are posted about 2 weeks ago by
Scott Garfinkle (smsdpg!seg@uunet.uu.net) in
comp.binaries.ibm.pc.d.

The new merged diff file, the new makefile and the new executable
are now available for anonymous ftp in
clover.ucdavis.edu[128.120.57.1]:pub/gawk202e.arc. I shall try to
put this version on simtel20. Please don't ask me to mail it to
you. I am too busy to do it right now.
