Right. Any idea on how to fix that then?

The binary that make ends up trying to use (orcc.exe) is useless,
because it's a win32 binary on a Linux platform. So the
architecture-neutral files can't even be generated.

Ah, yes. It seems that my workaround of setting ORCC= is the advised
solution. Still it would be better to autodetect a broken return value
of pkg-config. I could make a patch to orc.m4 that does just that, but
I can't seem to find the file in the orc git repo. Is orc.m4 managed
locally in the pulse tree, or is there some upstream that improvements
should also be submitted to?
