I installed swig 1.3.21 on SCO OpenServer 5.0.5. I successfully
compiled a simple example program "arith.c" using 'swig -tcl -module
arith arith.c'. I then tried to compile it with "gcc -I/usr/include -c
arith.c -o arith_wrap.c" and got the error "Parse error before
Tcl_Obj".

I then installed tcl version 8.1.1 from the SCO ftp site and still not
the same error.

Any suggestions to get swig to work on SCO OpenServer 5.0.5?
