I agree totally with what you say and the configure.in thingy is what
I had done on my first attempt. However, you must realise that we also
need the prototype for backtrace( ) which doesn't belong to config.h
AFAICT.

The other choices with me were to either include platform.h or to
have conditional (on WIN32 being defined) code in natStackTrace.cc
that declares the prototype for backtrace( ).

What I can perhaps do is to have configure define HAVE_BACKTRACE
for Win32 (does Cygwin use win32.h as well or is it only MinGW?),
and then have natStackTrace.cc provide a conditional prototype for
backtrace( ) on Win32.

Or does anyone have better ideas?

Ranjit.
