I haven't tried --enable-shared with MinGW.  I assume without this  
flag the system compiles properly?

You can try removing the definition

    #define ___CAN_IMPORT_EXPORTED

from include/gambit.h and see if that improves things.  You can also  
try defining some of the other ___CAN_IMPORT_... symbols.  All of  
this information should really be determined by the configure script,  
but that's not the case currently.
