Yes, netpbm is portable. There is IMHO even a DOS version. But i think
that it would be better in the long run to have _one_ import program for
all image formats instead for the r.in.{png|gif|tiff|...} and
r.out.{png|gif|tiff|...}. This is much work to maintain and confusing
for users.

We discussed this some time ago on this list. But i can't memorize the
result. I faintly remember problems with the BSD flavours. There must be
a reason why Huidae Cho didn't include float.h i assume.

A side note to Markus: Please refer to Mac OS X, not to MacOS, as that
are two _very_ different things.
