Frankly but it *looks* like you are playing dumb here.

Look at the pkg.m4 file, specifically AC_ARG_VAR and AC_CHECK_TOOL
usage... I already mentioned this several time and I find it really really
hard to believe that you missed the references.

It means using a mechanism promoted and favored by upstream pkg-config for
the express purpose of cross-compilation.

Diego is probably right that this depends on SDK-specific wrapper scripts,
but I fail to see the relevance to the point that this is "the upstream
way".

#10507 dude. The bug is over a year old and the report over a month old...

Indeed I probably can set my non-standard WINE path. And you can set your
non-standard PKG_CONFIG_LIBDIR.

Instead, I just gave up, made some hacks. And I kept them for myself
because I don't push hacks to the tree on the sole basis that they fix my
build.

In Debian, it does. I got there by following the wiki Win32 compilation
instructions by the way. And they do claim to support my Debian version for
build.

This is getting nowhere. For the last time, this is the official way to do
cross compilation with pkg-config. The fact that your SDKs do not implement
it is not an excuse for making it impossible for that whose SDKs do.
Besides my build platform is supported according to the wiki.

Tell that to JB. That's coming from JB. And at least Ludovic confirmed
hitting the same problem.

That's an excuse for ignoring GCC's license, not VLC's license, and
unincidentally my copyrights.

[The rest is just trolling so I left it out.]
