You are a candidate for SLMA (Silly Little Macros Anonymous).

There are no dues.  Just get a sponsor and come to the meetings.
Take it One Day At A Time, and soon you will no longer be
sending innocent programmers poking through .h files in order
to figure out what "Catspace" means.

:-), in case you didn't guess.

But if you don't like the naked "1", how about this?

foo =  malloc( strlen(s) + strlen(t) + sizeof('\0'));

Tells it all.  And keeps the reader on track, not grepping around
for macros.
