Well, as far as I know, the 1401 series does NOT have binary 
data types, or floating point.  Just decimal integers, where 
an implied decimal point can be placed.  I think this would 
make a POSIX compliant C rather difficult to do.  But, of 
course, you could just implement what came naturally to the 
machine.  For a POSIX compliant implementation, you'd just 
about have to generate some kind of code interpreted by an 
interpreter that ran on the 1401 directly.
