Title: Added LC_MIN and LC_MAX to locale.h

Microsoft's locale.h defines two convenience constants, LC_MIN and LC_MAX for locale categories. These constants are especially useful for simply checking if a locale category is valid. Although OpenWatcom's categories are defined differently, it doesn't provide these two values.

Microsoft mentions them here: http://msdn.microsoft.com/en-us/library/vstudio/ftyz68a0%28v=vs.120%29.aspx

While not necessarily standard, it certainly doesn't hurt anything including them (it helps to allow Python to build, for example).
