Changes made to CGIS code 6/10/99 following
email exchange with Bill Wall and discussion
with Jeff Newmark. Difficulty was in compilation
on Sun Solaris system. This file details changes
made between CGIS versions 4.0 and 4.1.

Changes were made in the following files (details below):
 aacgis_idl.txt
 make.solaris
 pstartup.pro
 startup.pro
 uidl.csh
 
and the link_osf1 file was deemed to be generally
applicable to Unix systems and moved to link_unix

Differences (old vs. new) are as follows:

aacgis_idl.txt:

< make.solaris, make.vms, make.osf1, make.irix, and make.alpha) are provided to
< facilitate compilation of the C code.
