I'd like to add support to cygport for dependencies with version
relations. In the course of working on this, I was led to question the
behavior of mksetupini when a PVR.hint file contains both a 'requires:'
and a 'depends:' field [*].
Currently, the 'requires:' field gets propagated to the 'requires:'
field of setup.ini, and the 'depends:' field gets propagated to the
(version-specific) 'depends2:' field of setup.ini. When setup parses

setup.ini, the 'depends2:' field takes precedence over the
(non-version-specific) 'requires:' field.
The net effect, then, is that the 'requires:' field of PVR.hint is
ignored. Wouldn't it make more sense for mksetupini to fold the
Almost. It's not being ignored by setup versions <2.884.
I'd like to do something to stop those versions from being used in a
moderately graceful way, but that hasn't happened yet :S

Alternatively, maybe we shouldn't allow PVR.hint to contain both
'requires:' and 'depends:'
Yeah, this isn't very useful, and should probably be disallowed.
Certainly, I think it would be fine for cygport to just generate
depends: and let mksetupini worry (or not) about older setup versions.
[*] I can't think of a good reason to create such a .hint file, but it
appears to be allowed in
