surely not *all* PC processors - what about the Alpha's? I realise that 
they're not really widespread, but they are out there. I suppose you could
also count PowerPC in that vein.
PICKY_MODE = FALSE

#Probably the more pervasive reason, however, is that there exists A

#IIRC, the original CRAY C compiler used a 32-bit long and a 64-bit

Yes, and just to confuse the issue, the later compilers used 48bit as the
default. Although you could say '-i64' on the command line to promote these 
variables
all to 64bit.

#IMHO: C should have included standard data sizes, as well as it's generic

Agreed. Personally I cannot see a problem with :
short = 8bits, int=16bits, long=32bits, (long long = 64 bits)
other than possible problems when Merced et al are around, rumour has it that 
this
is 128bit native? So what would this be - "long long long" perhaps?
