Thanks for all the suggestions.  For several reasons I won't go into (they
relate to the specific task I've been given to do) I took the followng
suggestion.

I got the various files supporting 'picttoppm' & 'ppmtopict' from
cayuga.cs.rochester.edu (in file pict-ppm.tar.Z) & added them to my pbmplus
subdirectory 'ppm'.  I added those two program names (and their respective
'man' file names) to the Imakefile in 'ppm' & reran xmkmf to create a new
Makefile.  Then I did a rebuild.

I used PixelPaint on a Macintosh to create a new image file, by importing a
ClipArt file in MacPaint format into a PixelPaint/PICT2 file & adding about
20 colors to various figures.  I used Tops software to transfer the file to a
Sun3 into the 'ppm' directory.  (As a double-check I used Apple's file
interchange program to copy the image file to a 5 1/4" diskette, took that to
an IBM AT, and ftp'd the file to the Sun3.  The 'diff' program showed no
differences.)

After running 'picttoppm' & 'ppmtoxwd' I used 'xwud' to display the X window
dump version of the image file.  Despite two warning messages from
'picttoppm' about two opcodes the program didn't handle, the resulting image
seemed to be a faithful reproduction of the Macintosh image.  (Out of
curiosity, I used 'ppmtorast' & 'xloadimage' & got an apparently identical
image on the Sun3.)
