I agree -- I also had the thought of changing to an if statement after
I sent my mail.  Much better than the switch since it can't break.

I suspect that if float is 8 bytes then int will be too.  Just char,
short, float, and double should suffice.  If the 4-byte version is
missing it will just fall back on the default (slower but otherwise
OK), and if the C compiler doesn't support shorter data items then
probably the user won't be using them anyway...
