We do not implement that. It is rarely usefull and only obfuscates code
by separating the locale setting from the actual output that requires it.
The C++ model is much more usefull...

Use printf_l(3) and friends. Most typical use in software is to force the
C locale, which is even simpler by using LC_C_LOCALE, like:

	printf_l(LC_C_LOCALE, "this is a float value: %.2f\n", 2.5f);
