Posting-number: Volume 20, Issue 18
Archive-name: dvi/patch01
Patch-To: dvi: Volume 19, Issue 64-66

This is the first bug-fix release for dvi.  The following is a list of
modifications contained in this patch:
    - dvi has been ported to Sparc - minor ifdef needed,
    - version string was slightly modified so say_hello() in
          main.C works,
        - also looks for fonts such as /path/cmr7.300pk and cmr7.300gf,
        - Makefile was modified to allow overriding the default font
          search path.

To apply this patch cd to the dvi source directory, unshar this file
and the "patch < patch-1.6-1.7".
