Unfortunately no dice... removing the lines just brings me the next error:

make[1]: *** No rule to make target 'Files\Microsoft', needed by 'all'

(which is probably totally unrelated to my previous problem?)

I think I will have no choice but to delve into the internals of the 
mysterious makefile, but first I will have to
get my girlfriend to leave the house to get the time to do so ;-) If I find 
out what's causing my troubles I will
post the results here.

Sorry about that, I was not aware of this policy, won't happen again. Thanks 
for your help so far!
