The file "control.c" contains Fortran-callable GKS control routines
written in C.  It is created from the file "control.fc" by the "fortc"
utility (which is part of the distribution).  This is done because
there is no standard for how Fortran code calls C code. "control.fc"
contains code that is independent of the system's calling conventions;
The "fortc" utility understands Fortran/C calling conventions for most
systems; and the resultant "control.c" contains code that follows the
conventions of the system.

In order to diagnose your problem, I'll need more information.  would you please
do the following:

    1.  Go to the top-level source directory.

    2.  Execute the command "make distclean".

    3.  Remove the file "config.cache" if it exists.

    4.  Set your environment variables as before.

    5.  Execute the configure script.  Redirect standard output and
	standard error to the file "configure.log".  If an error message
	occurs in the output, then stop and send me the file.

    6.  Execute the command "make".  Redirect standard output and
        standard error to the file "make.log".  If an error occurs, then
        stop and send me the files "make.log" and "configure.log".
