With this change, cairo now cannot be built on OS X 10.4 with the --enable-quartz-font flag, whereas this worked before:


:info:build cairo-quartz-font.c: In function '_cairo_quartz_init_glyph_path':
:info:build cairo-quartz-font.c:548: error: 'CTFontRef' undeclared (first use in this function)
:info:build cairo-quartz-font.c:548: error: (Each undeclared identifier is reported only once
:info:build cairo-quartz-font.c:548: error: for each function it appears in.)
:info:build cairo-quartz-font.c:548: error: expected ';' before 'ctFont'
:info:build cairo-quartz-font.c:563: error: 'ctFont' undeclared (first use in this function)
:info:build cairo-quartz-font.c:563: error: implicit declaration of function 'CTFontCreateWithGraphicsFont'
:info:build cairo-quartz-font.c:564: error: implicit declaration of function 'CTFontCreatePathForGlyph'
:info:build cairo-quartz-font.c:564: warning: assignment makes pointer from integer without a cast
:info:build make[3]: *** [cairo-quartz-font.lo] Error 1


Would it be possible to keep the previous code for OS X 10.4 and use the new code on OS X 10.5 and newer?
