Mach-O and C++ static template definitions

[Michael Rosellini <m at netcabletv dot org>]

Presently, under OS X, GCC requires explicit definitions for static 
template data members.  That is,

	template<typename T>
	struct foo
	{
		static int x;
	};

	template<typename T>
	int foo<T>::x;

causes problems at link time.  An explicit definition of the x member 
must be given for each instantiation of foo<T>, such as,

	void funfun()
	{
		foo<int> f;
	}

requires a definition

	template<> int foo<int>::x;

somewhere if it is to link correctly.

Implicit definition of static template data members works properly for 
ELF.  Is there an ETA for support for this functionality for Mach-O?  
Or, have I overlooked existing support?

(PS: I interpreted the documentation for -frepo as indicating that it 
offered a solution for this problem.  Experimentation suggests that I 
was wrong.  Please let me know if I'm mistaken; but this does not 
answer my question, as -frepo results in an unacceptably long build 
process.)

Thank you,
