Well, for me the kdevelop.kdevprj definitely works even before the patch, but 
then kdevelop is an automake-managed project -- I don't know if it changes 
matters. An empty custom project doesn't have any Makefile.am files, so 
please let's start with an empty one first.

And yes, it seems to work all right with kdevelop.kdevprj after the patch, 
too. The patch affects single-file compiles *only* and makes make use correct 
options (previously, make didn't get any options at all as far as I can tell, 
at least not on the command line - maybe configure put some magic into the 
makefiles?)
