I have successfully made a Windows DLL for my Decimal Plugin. I
installed MinGW and MSYS on my Parallels Windows XP virtual machine.
This brought a UNIX like environment to Windows. I then was able to
make the gmp-4.1.4 libraries for Windows i386. I did not use the
latest gmp-4.2.2 release because that makes unusable libraries on my
Intel iMac. So I've used 4.1.4 because a package exists for Ubuntu
Linux and the Intel iMac, and I wanted consistency.
Once I had the gmp static libraries, I used the same source files
that successfully made a Linux shared library using Ubuntu. I edited
the makefile so as to use the new paths for the libraries. For
simplicity, I dropped gmp.h and gmpxx.h into my source folder and
changed the includes to #include "gmpxx.h" and #include "gmp.h". Also
I edited the Plugins SDK files to comment out QT references, since
mine is a purely mathematical plugin. In particular, I had to comment
out all the conditional #if X_Window ... #endif, since they gave
errors in the make. Here is my actual makefile (Note that /c is the
C: drive in MSYS):
# makefile

# Usage:
# make all

# This is the makefile for the Decimal plugin.
# The first part, suitably edited, is from Plugins SDK Box Control

Sometime after the creation of the DLL and exiting MSYS, Parallels
itself crashed. I don't know if this was due to MinGW and MSYS, or if
was the result of Parallels Build 5160 running under Leopard on my
Intel iMac. There is a Parallels beta out now, which I haven't tried.
Anyway I reinstalled Parallels and everything now seems to be OK.
