[cairo] Unable to compile cairomm 1.7.0 (OS X fink)

[Asko Kauppi]

Oops, that was interesting.

Seems libsigc++ 2.5 is prepared for this:

	http://ardour.sourcearchive.com/documentation/2.5/functor__trait_8h-source.html

#ifdef nil
  /* stupid OS X, defining nil */
#undef nil
#endif


But current fink version is 2.2.3.   I will contact the maintainer to  
make sure (s)he is notified.

Seems fitting the same first aid block in front of including <sigc++/ 
slot.h> in both cairomm/fontface.h and cairomm/surface.h does the same  
trick.

Thanks!
