Have you tried to use double quotes instead of single quotes?
I noticed that there is a difference between command prompt
in Windows and shell prompt in Unix. Can't remember which
one had to use on Windows, though.

With this weekend's HEAD I noticed that the -h command does
strip the headers from the input images, but the command used
to create the output is still there in full length. I can understand
that this is the desired behaviour. If you plan to combine a large
number of pictures I would recommend another pcomb command
with a single input file just to strip this header as well.
