The reason I asked is that the supplied makefile has the lines:

#relax error checking
XGCC=$(XLGCC)

but the code will build with very extensive warnings turned on, so I
was thinking those lines could be removed.  Looking again though, I
would say those lines could be for dbgcom.c, if that's so then they
should stay.

Sorry, I should have been clearer.  I want to generate some crash
dumps to test symify with to see if anything is broken.  This should
not be difficult ;-) but I am open to suggestions for things to try.
So far the following code is pretty successful in causing a crash :-)

#include <signal.h>
int main(void)
{
  raise(SIGABRT);
  return 0;
}

To test the robustness of symify I was going to corrupt some .exe
file.  Again, I am open to suggestions on this.
