And on gcc for linux too; sadly on MS compilers we get this:

Type Name     Bytes            Other Names   Range of Values
double        8                none          1.7E +/- 308 (15 digits)
long double   same as double   none          same as double

Anyway, I've sent a patch (not to the list) for the other yasm VC8 build 
file issues which I mentioned.

Thanks,

Charles.
