Anything can be a main subprogram (the restriction was for 83), however 
only parameterless library procedures are guaranteed to be portable:

LRM 10.2(29):
An implementation may restrict the kinds of subprograms it supports as 
main subprograms. However, an implementation is required to support all 
main subprograms that are public parameterless library procedures.

How to define the main subprogram (including the case where it is not a 
library procedure) is implementation defined, i.e. RTFM!
