typedef'd enum specifying type

[trillianjedi]

Hi all,

I'm having trouble setting the size of an enumerated type when it's set as a typedef:-

typedef enum 
	{ MT_NULL, MT_ACK, MT_PING, MT_BYE, MT_GETINFO } 
messageType;

The above is a condensed version - there are more message types, but way less than 256 of them and I'd like to tell the compiler to treat this as a byte rather than the default int (I'm using GCC).

Is there a method to do this as inline code? I have other enumerated types which are ints and work fine - I don't want to break those by setting a global compiler value.

Many thanks.
