Of course I did :) Well, splitting at "-" is just as bad as splitting at
" ", it may be inside a path as well.

Anyway I'm going to build apr tomorrow locally and put it into a path
with spaces, lets see what apr-config tells me afterwards (I'm guessing
it will give me -Lfoo bar or -Lfoo\ bar, but no quotes).

Well, you can if you ignore quotes of "", i.e. something like 

"foo\"bar"

cannot be parsed by a regexp. And now that I said that I need to add a
todo-item for the qmake parser in Kdev4 which obviously can't parse
quoted " :(
