I have the impression that what makes "make" to exit is not the inexistant 
header file ("floatingpoint.h") which OTOH, I cannot find it available 
anywhere in debian repositories for linux kernels, but the last warning 
(xbindkeys.c:498:) but any developer will tell, I'm a plain user :-)

Interesting... let's see:

http://www2.its.strath.ac.uk/courses/c/subsection3_13_3.html#SECTION00013300000000000000

So brackets for searching the file on the usual library path and quotes 
for local header files :-)
