Dear Karl,

  I installed xdvik-1.4 on an SGI Indigo R3000 with IRIX 4.0.5F and
the ANSI C 2.0.4 compiler yesterday.  It worked well except for two
peculiar interactions with MakeTeXPK (MakeTeXPK invoked automatically).
  It appeared that the xdvi program wanted font pixel files at 328 pixels
but the MetaFont program created files at 329 pixels. So each time xdvi
ran on the same dvi file it repeated the calls to MakeTeXPK.  I believe
I removed the confusion by modifying a float-to-integer conversion in the
file font-open.c.  In the function font_open, I changed the
kpse_find_glyph_format function call to

   kpse_find_glyph_format( font, (unsigned)( dpi + 0.5 ),
                           kpse_any_glyph_format, &file_ret );

  Also, unless I defined the environment variable XDVIFONTS with the pixel
file subdirectory, xdvi invoked MakeTeXPK, and MakeTeXPK, knowing the
path to the pixel file independently and explicitly, announced that the
files already existed.  After calling MakeTeXPK, the xdvi program seemed
to find the pixel files and it ran great, but the monologues from MakeTeXPK
appeared pointless.  (The texfontdir variable in the Makefiles for both
xdvik and kpathsea were correctly defined as /usr/local/lib/tex/fonts and
the pixel files are in the subdirectory /usr/local/lib/tex/fonts/pk.) I
suppose that the kpathsea functions are meant to search down the tex font
directory tree, so I figure that xdvi is meant to find these fonts in the
pixel file subdirectory.  But maybe I'm wrong.  Anyway, I gave up on this
one when I found that defining XDVIFONTS stopped the chatter.
  I appreciate your efforts in making this great program available to people
like me: I save lots of paper and time using xdvi - thank you.

                Best Wishes,
                Brent Ewing
