No, gcc-2 was a package of the old gcc-2.95.x compiler.  It was pulled
from the distribution because of bugs.  gcc is currently version 3.3.3.

This is not a gcc problem at all.  Cygwin will let you open COM1, COM2,
etc., but it will treat them as regular files.

If you are trying to use POSIX functionality (termios, etc.) with that
file descriptor, please use the corresponding POSIX device name listed
here instead:

to open the port.  Doing so should eliminate your problem.
