MingW help?

I am trying to build Torque using the latest MingW/MSYS environment (running under WinXP). I am using the latest snapshot of Torque, downloaded from CVS. TorqueDemo compiles fine, but I am noticing an error in map2dif (I presume there are other problems, but this is the first that I have encountered).

First, I did the following (within MSYS):
make -f mk/configure.mk OS=WIN32 COMPILER=GCC3 BUILD=RELEASE
make clean
make all

The error I encounter is:

--> Compiling map2dif/exportGeometry.cc

and so on.

Has anyone encountered this? Is there a fix? Thanks!
