Surely the GO32 target bit is your responsibility, though, DJ? It's
not really a change to the core of GCC, merely the DJGPP bits.

I tried the above patch, compiled it, and got my locked section thing
(I've posted it to the group somewhere) to work using the LOCKED_VAR
and LOCKED_FUNC 'attributes', defining a few LOCKED_VARs and a
LOCKED_FUNC and calling them etc.

Is there a way to tell if they've actually been locked?

If I can prove that it is locking what it should, I'd like to put it
forward as a feature for the next DJGPP release, if The Experts want
it; GCC capable of producing custom sections, the DJGPP.LNK I made or
something in a similar spirit, the LOCKED_* defines from sect.cc, and
the inclusion of the locking function in crt1.c

Regards,


ABW
