[gambit-list] problems with development release

I just downloaded, untarred, compiled, installed gambc-v4_6_0.tgz

But when I tried to use it Space-invaders-src-v1.0.tgz I got errors that 
look like C/C++ compatibility problems.

I compiled and installed gambit using C++; specifically, the g++ 
compiler.

I had to modify the space invaders makefile to recognise that gambit was 
installed at /usr/local/gambit, and to tell it that my C compiler was 
g++.


## compilers
GSC=$(PATH_TO_GAMBIT)/bin/gsc -:=$(PATH_TO_GAMBIT)
CC=g++

## Gambit-c
# PATH_TO_GAMBIT=/usr/local/Gambit-C/current
PATH_TO_GAMBIT=/usr/local/Gambit-C


I then performed a
        make clean
in the space-invaders directory to clear out the effects of mismaking 
with the wrong PATH_TO_GAMBIT and the wrong CC.

Upon doing
        make OS=linux UI=glut
The errors I got were

My guess is that one crucial macro within the gambit include files fails 
to deal with 'const' properly.  Or is there some obscure way I'm getting 
C code instead of C++?
