[Coco] CMOC C-like compiler now supports float under Color Basic

[Pierre Sarrazin]

Hi,

Thanks for those suggestions. I'll have to think about that. But for now,
users who want to "future-proof" their code could use something like
"typedef float mbf40" and write their program using that name.

I don't personally plan to add other floating-point formats in the
foreseeable future. I will probably prioritize adding a (32-bit) 'long'
type, but I have no timetable for that.
