Is this problem limited to the Cygnus GCC port, or does the DJGPP port
included on the CD take that much time as well?

If it's only the Cygnus port, you will have to write to some
Cygnus-related forum, where people could help you.  This forum is for
discussing DJGPP ports.

Please try compiling it with the DJGPP port and see if the problem
persists.

There's no ``old DOS 16-bit emulation'' in the Cygnus ports, AFAIK.
