State-Changed-Why:
    Paolo, a bit of a clarification.
    
    This issue cannot be reproduced on linux, because it uses the gnu locale model that actually implements named locales. For other configurations, namely cygwin, a different configuration is used, ie the generic config. In this configuration, the bug can be reproduced.
    
    The generic config does not attempt to create accurate named locales and instead all "named locales" use the "C" locale. Because of this, attempts to create fake or non-existent named locales (as in the test case) will "succeed" in that they are created (but contain only "C" locale info.)
    
    This is a QOI issue, but not a bug. The standard allows implementation-defined behavior on this point: the generic locale model's defined behavior is to allow it.
    
    Funding to implement a more useful generic locale model is not forthcoming. Patches to implement it have also not been forthcoming. When either of these change, the generic locale model will be more interesting.

>Description:
Constructor `explicit locale(const char* std_name);' is
contrary to standard. Source documentation
`22 - Localization library [lib.localization]',
section 22.1.1.2 (6-8).
For example, running the following program tnum should
print: "locale not found"
>How-To-Repeat:
#include <locale>
#include <iostream>
int main()
{
	using namespace std;
	const char* locname = "asdfghjkl;'";
	try {
		locale loc = locale(locname);
	} catch (...) {
		cerr << "locale not found" << endl;
		return(1);
	}
	cerr << "locale found" << endl;
	return(0);
