There is a newer version.  Here is the output from the above on my system,
a 3B2/400 running SysV 3.1.2:


$ fpcc -V main.c
cc: command - C Compilation System, Issue 4.2 4/29/87
comp: MAU compiler - C Compilation System, Issue 4.2 4/29/87
as: assembler - C Compilation System, Issue 4.2 4/29/87
ld: link editor - C Compilation System, Issue 4.2 4/29/87

The newest is 4.2.

$cc -V main.c
cc: command - C Compilation System, Issue 4.2 4/29/87
comp: FPE compiler - C Compilation System, Issue 4.2 4/29/87
as: assembler - C Compilation System, Issue 4.2 4/29/87
ld: link editor - C Compilation System, Issue 4.2 4/29/87



This is from a 3B2/400 Running SysV 3.1.2 with Advanced Programming 
Utilities Issue 1.2
