How is that? Can you be more specific.
I just compiled that old version with djgpp 2.04 and gcc 4.8.1.
But I had to make 1 change; the ./util/dj_err.exe program needed
to be recomiled with:
make -f errnos.mak dj_err.exe
before doing a "configur.bat djgpp" in ./src. That's because djgpp 2.04
did change some <errno.h> values since dj_err.exe was built in 2006.
And the '-gcoff' flag in src/Makefile.all should be dropped. Otherwise
I'm not aware of any programs with this old package.
I know it's been a long time (2006) since my Watt-32 was released
last time. It's no longer a demand for any DOS versions of it. But
I'm still working on it from time to time. Expesially supporting Win32
and Win64 targets using esp. MingW.
But back to the OP's problem with the disassembling. I jut tried with
the Watcom disassembler wdis. It produced this output which seems
correct to me:
