[cairo] building with --disable-script boken

[Dave Yeo]

Hi, after configuring with --disable-script the build breaks in 
cairo-surface-observer.c

In file included from cairo-script-private.h:41:0,
                  from cairo-surface-observer.c:47:
cairo-script.h:86:3: error: #error Cairo was not compiled with support 
for the CairoScript backend
...
cairo-surface-observer.c:1626:5: error: implicit declaration of function 
'cairo_script_surface_create'
cairo-surface-observer.c:1626:5: warning: nested extern declaration of

Also OS/2 needs to include sys/time.h to get struct timespec etc. I'm 
not sure where the best place to include it is.
