And don't forget, newer versions of gcc support the hiding of
unnecessary exports when code is compiled with -fvisibility=hidden and
#if __GNUC__ > 3 || \
(__GNUC__ == 3 && (__GNUC_MINOR__ > 3 || \
(__GNUC_MINOR__ == 3)))
/* Export functions (gcc) */
#define CAIRODECLSPEC __attribute__ ((visibility("default")))
/* Import functions (gcc) */
This will give the same result as the __declspec(dllexport) on win32,
see http://www.nedprod.com/programs/gccvisibility.html for more info.
You might want to check for __ELF__, as well, since the gcc visibility
thing only works on "some" ELF targets.
