interesting note:

Use C on a Cyber 180 arch. running NOS/VE it looks like this:

char   = 8 bits
short  = 64 bits
int    = 64 bits
long   = 64 bits
float  = 64 bits
double = 64 bits

This might have changed with the new C (CV2) compiler..but we have yet to
get it.

(the system software is in another language :)
