Subject: loading rubygems at startup without RUBYOPT

Hi,

By linking following extension library statically, rubygems.rb will be
loaded even if no -rubygems option is in RUBYOPT nor command line.

	#define RUBY_EXPORT 1
	#include "ruby.h"
	void Init_rubygems(void)
	{
	#ifdef IGNORE_NONEXISTENT
	    static const char so[] = "rubygems.so";
	#endif
	    rb_provide(so);
	#ifdef IGNORE_NONEXISTENT
	    rb_require("rubygems");
	    rb_ary_delete(rb_gv_get("$\""), rb_str_new2(so));
	#endif
	}

and `make EXTSTATIC=rubygems' if you put the above under ext/rubygems directory.

Just my 2JPY.
