If I recall correctly from reports from a Cygwin user there should not be
any gd problem on Cygwin.  However, there are Cygwin limitations, and to get
any good results on that platform at all (at least for the Cygwin version
from roughly a year ago), Walt should follow the special Cygwin configure
directions in our INSTALL file. Also, he should note there is a workaround
there for a special Cygwin g77 problem for getting access to command-line
arguments.  I doubt that will be a concern for other fortran compilers
so long as they have access to the iargc and getarg fortran library
routines for finding the number of arguments and actual arguments.

Walt, I emphasize the problems we encountered a year ago may now be fixed in
Cygwin so some additional test ./configure/builds may be required to really
find out what today's Cygwin limitations are.
