Subject: [SDL] Changing, at least some, anonymous enums to named enums.

Howdy,

Could, some if not all, enums be named rather than being anonymous enums?
I ran into troubles with the enum describing event types in SDL_events.h.
The problem is that an anonymous enum cannot be used in C++ templates like
so:

enum { C };

template< typename T >
void
f( T ) {
}


f( C );
