I'm (finally) working on updating the gzip in Debian to something newer
than 1.6, which caused me to stumble over the addition of the do_chown
function in gzip.c. That's because I need to build both native Debian
and Windows binary packages, the latter in support of a portion of the
Debian installer system that has something to do with Windows.
The problem is that mingw doesn't provide uid_t or gid_t definitions,
perhaps just because there isn't really an equivalent ownership
construct in Windows?
Yes, that must be it. I installed the attached into gzip master on Savannah;
does it fix things for you?
