Yes, we can run them via "wine". Perhaps we could have something like
   if linux && target_mingw
       RUNTARGETEXE="wine"
   else
       RUNTARGETEXE=""
   fi
in the makefile?

The makescript attempts to run cross-compiled binaries in a number of
places. The only place that matters for a straight "make" is q2c, so I
replaced
  /.../q2c
       ./src/language/lexer/q2c $< $@
with
       wine ./src/language/lexer/q2c$(EXEEXT) $< $@

I have likewise replaced pspp.exe with "wine pspp.exe" to get "make
check" to run most of the tests.

It would be possible to change the Makefile so that .exe files are run
with wine and .sh files are run with /bin/sh, but I have not done this
yet.

For obvious reasons I am using SUPERVISOR="wine". I'll have a look at
the debug options in wine.

I don't understand those segmentation faults. Usually if a program
running in wine segfaults, wine itself will dump some diagnostic data.
How does the Makefile detect segfaults?
