This is the unix port I have installed on FreeBSD and is the tool-set I
would like to use for win32 cross-compiled apps.

The process here is to build a shared object for two platforms that
contains foreign-functions callable from swi-pl on win32 and unix.
I may be missing something fundamental but what I am really trying to do
is embed swi-pl in a win32 app and a unix app but from a unix
environment. So the makefile would do something like the above but would
also embed the runtime. So it's not prolog calling a shared object but
an app using the prolog runtime.
Ideally you would be able to call 'plld' to generate both versions of
the app: What I haven't been able to do is compile the app using
mingw32-gcc on unix and embed the win32 runtime into it.
So one question might be what is the win32 runtime and how do I glue it
to a (cross-)compiled application??
Does lipl.lib contain the runtime or is it plcons.exe?
Would it work compiling an app and linking with libpl.lib then
concatenating the plcons.exe file??

It is the first example of doing this I have seen - many thanks.
