[cairo] Problems compiling cairo under cygwin

[Adrian Johnson]

Cygwin 1.5 does not have have the wide character stdio functions. Cygwin 
  1.7 does have these functions [1]. I've tested cairo git with cygwin 
1.7 and after fixing some bugs it works fine. You will need to add 
#include <wchar.h> to cairo-win32-surface.c The other bug fixes should 
not be applicable to 1.8.8.

Cygwin 1.7 already includes a cairo 1.8.8 package but the windows 
surfaces are not compiled in.
