Okay, it turned out this was due to a stupid typo, entirely my fault.
Sorry I wasted everybody's time.

The binary built with the v2.03 branch of go32-nat.c enabled does
allow to resume the debuggee after a signal.  But I have another
problem: SIGQUIT (generated by pressing Ctrl-\) is reported as SIGINT,
even though I fixed go32-nat.c to know about fake exception 0x7a
generated by SIGQUIT.

It appears that this is somehow connected to this fragment from
dbgcom.c (in `dbgsig' function):

     /* I still have no idea how to get the exception number back */
     /* just keep the fake exception value */
     signum=0x1B;
     __djgpp_exception_state->__signum=signum;

Can someone please explain what's the story behind this snippet?  Why
is it a problem to get the original exception at that point, and what
are the implications of this?  Does it mean, for example, that SIGALRM
will also be reported as SIGINT?
