How to make Xgcl for Solaris

A few changes are needed to make Xgcl for Solaris because of the
shared X librarv.

1. Get gcl-2.2.tgz, gcl-2.2-fixes.tgz, and xgcl-2.tgz from
   ftp.ma.utexas.edu /pub/gcl .

2.  Make GCL-2.2: unpack gcl-2.2.tgz using gzip -dc gcl-2.2.tgz | tar xvf -
    and then gzip -dc gcl-2.2-fixes.tgz | tar xvf -
    and then do the make as specified.
    Put xgcl-2.tgz in the gcl-2.2 directory and unpack it.

3. Edit xgcl-2/makefile and make the following changes:

X_LIBS  = -L/usr/local/X11R6/lib -R/usr/local/X11R6/lib -lXaw -lXmu -lXt -lXext -lX11

IFLAGS  = -I/usr/local/X11R6/include

   Change the file paths as needed for your environment.

4. Edit the makefile in each of the directories gcl-2.2/, gcl-2.2/o/,
   and gcl-2.2/unixport/ as follows:

   Remove the directive   -static   from the CC line.

5. You should then be able to perform the make of xgcl-2.
