[Win32utils-devel] Win32API patch?

Hi all,

Passing a Fixnum when you should have passed a String (pointer) causes a
segfault in Win32API.

I've already reported this on RubyForge (Bug #3904):

require 'Win32API'
RegFormat = Win32API.new('user32', 'RegisterClipboardFormat', 'P', 'I')
RegFormat.call(1) # Boom!

I've traced the error to line 194 in Win32API.c:

ret = ApiFunction(param);

Where ApiFunction is defined as:

FARPROC ApiFunction = (FARPROC)NUM2ULONG(obj_proc);

Any idea what the patch should be?  I'd rather get a TypeError than see
a segfault.
