They both use the same name. This means that they might have both been
put in by the same programmer. If there is a history of old versions
of BasiliskII source code, then we could find out when the mysignal
got added to autoconf, and perhaps that will give a clue as to who
added it and maybe the other mysignal was added at the same time.

I suggest that you add the change in the same way that one normally
makes such changes in Debian.

This is probably done with the config files. Note that "HAVE_DEV_PTMX"
appears in:

  Unix/config.h.in
  Unix/configure
  Unix/configure.ac

I do not know how these files work, but I do remember that one or more
of them is created based on one of the others, and I'm pretty sure
this happens in the "autogen.sh" or "configure" step of the build
process.

Whichever one is the "original" configure file, needs to be edited so
that it tests for Debian and disables the define of HAVE_DEV_PTMX if
the Debian test is true.

Once you determine the best way to change the right config file, then
report the details back to this list. There are people on this list
who can update the source code server to reflect the bug fix, once
they are told what needs to be changed.
