Conflicting definitions for copy_fh

[kyz]

copy_fh is defined the same way in its prototype and its implementation: static int copy_fh(struct mspack_system *, struct mspack_file *, struct mspack_file *, size_t, unsigned char *, int)

It is called with the fourth parameter being unsigned int rather than size_t. As size_t is the same or higher rank than unsigned int, and both are unsigned, it should be promoted to size_t without warning or error.

Please supply the error output by gcc, and also supply the output of changing "gcc -c" (compile) to "gcc -E" (preprocessor output) so that the definition of size_t is revealed.

The declaration of copy_fh is on line 38 and the definition is on line 377. The declaration and definitions are not the same, gcc complains with

OK, you are using an outdated libmspack. This was fixed in 817f2a2 and released in libmspack v0.10.1alpha.

I believe this happened: you skipped the README on the front of the repository, went to the "releases" page and clicked whatever was first in the list. This gave you a snapshot of the repository for cabextract v1.9.1, and did not give you a snapshot of the repository for libmspack* v0.10.1alpha, which is what you need, if for some reason you don't want to go to https://www.cabextract.org.uk/libmspack/ where libmspack is actually released.

Solution: Read the README and obtain libmspack from https://www.cabextract.org.uk/libmspack/

If you are doing packaging for a distro, please ensure https://www.cabextract.org.uk/libmspack/ is where the package comes from, not a third party such as GitHub.
