on1 construct

[Jerry Aguirre]

How about:

#define on1(X) static char first_time_in = TRUE; if ((first_time_in) && (!(first_time_in = FALSE)))

function ()
{
    on1() {
	bla;
	bla;
	...
    };
    etc...
}

The evaluation of the && will reset the flag the first time thru.
Because the reseting is done as part of the test the braced part of
the code is not affected.
