But it works without any problems here. You don't need to add
/usr/include or /usr/local/include to the CXXFLAGS because they are
always included.
I can't imagine a reason why the includedir should not be a "standard
directory".

So your imagination is limited. Nvertheless, it is no good practise to expect something to be included by default.
As long as INCDIR or PREFIX can be changed in Make.config, this *has* to be considered when creating vdr.pc. I'm not requesting a feature, I'm just providing a bugfix.
