Hi Markus,

sorry for being late in answering - have been busy.

I've rewritten your patch so that it doesn't fire any subshell, and it
only scan directories when compiling or linking - not each time a makefile
is read - to prevent degradation of performance on make clean etc.

I've made the patch OS X specific, then committed to CVS.

Let me know if it works for you, or if you have got any problems with it.
