I can add a snippet about the CPLUS_INCLUDE_PATH variable, but I don't the root cause of why the variable causes pkg-config to gag.

I'm nowhere close to being qualifed to write something about CXX/CFLAGS. Somebody else (not you) should provide a paragraph addressing those variables.

I don't know where to begin with respect to addressing other variables. Perhaps if several people here add their two cents or euros to what they use and what they avoid I then could massage that information into something useful. :)
