Undocumented Feature

[Allan Fleming]

Under 3.2 using the f77 compiler - when porting a program from VMS I 
discovered that doing the following:

f77 -vms test.f

caused the -onetime option to be invoked - producing rather non-VMS like
behaviour. 

(please don't say RTFM - I did and the manual doesn't mention that 
-vms is now -vms_cc and that -vms no longer appears to be a valid 
switch, if the manuals agreed with the online man pages or the compiler
warned me that -vms was no longer supported I may have saved a fair bit 
of time)
