Good question. There are 530 C files...
I will follow the debian analysis at
http://packages.debian.org/changelogs/pool/main/n/netpbm-free/netpbm-free_10.0-12.2/libnetpbm10.copyright
and write down my findings here for future reference.
There is
fiasco: no license information inside netpbm, but it is distributed on its own as gpl2+, see
https://github.com/megatherion/Fiasco/blob/master/README
mdatopbm: gpl2+
pamstretch: gpl2+
pbmpage, pbmtoppa: This appears to be gpl2 only. The C files state:
* Copyright (c) 1998 Tim Norman. See LICENSE for details
And LICENSE is GPLv2.
So I will stop here and push as gpl2.
