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

[Mathieu Bouchard]

As there is no other 40-bit float format that I know of, and as the other MBF 
formats (32 and 64 bits) have probably never been used with the CoCo and quite 
rarely since QuickBasic 4.0, I think it is quite safe to just name it 
float40 and not mbf40.
