Package: macutils

Severity: normal

Dear Maintainer,
Using macunpack from macutils to unpack a CompactPro archive results in an
error message
Header CRC mismatch: got 0x79c895e4, need 0xebae4ed4
However, the CPT file unpacks successfully using CompactPro 1.52 on an
emulated Macintosh.
It appears the problem is that macunpack uses (unsigned long) 64-bit integers
for the computation of the "Zip CRC", but the CRC computation of CompactPro
only uses 32 bits.
Patching several unsigned long -> uint32_t values allows macunpack to decode
the archive.
(This was reported 'downstream' as
https://bugs.launchpad.net/ubuntu/+source/macutils/+bug/2136046)
I would be willing to develop a patch, however I am not particularly familiar
with the development and build process you prefer, and extensively updating
the 16/32-bit dependencies in the code potentially touches many files.
