How to detect GD in source code.

I've been writing a module, it is dependent on some GD functions, how
can I detect that GD has been installed PHP native?

I'm not talking about php code to see if the functions are available.

Is there a macro or something that will detect if GD is installed
native?

If not,do you have code that detects if GD or a GD function is
installed native?

Anything I can add to aclocal.m4 and/or configure.ac would be greatly
appreciated.

Taking a page out of Zend/zend_builtin_functions and the source code for the
extension_loaded() userspace function:

int gd_is_loaded = zend_hash_exists(&module_registry, "gd",

sizeof("gd"));

Anything I can add to aclocal.m4 and/or configure.ac would be greatly

You could adapt the stuff in ext/gd/config.m4 to look for and link libgd
yourself...
