I am getting a strange error using djgpp's gcc 2.3.3 compiler for the DOS      
environment.  I am using a makefile with the following compiler arguments:

  -Wall -xc++ -w -DMSDOS -m486 -Wmissing-prototypes -Wstrict-prototypes -O
        
This should force the use of the g++ compiler, however, I also get the 
following error

  undefined symbol MyScreen(const char *, int) referenced from text segment

The prototype looks like:

  void MyScreen( const char *picfile, int index = 0 ); // in type.h

The function Definition looks like:

  void MyScreen( const char *picfile, int index )  // in shade.c

And the calls look like
  
  MyScreen( "test.out", i );  // in sphere.c

I do not think that the problem is the extension of the file.  Any other 
suggestions?

thanks in advance,
