I'm pretty sure IBM C/370 V2.0 didn't support it, depending on
what you call "support".  It is likely you can add an extra 5
parameters to the end of main, with very few if any compilers
actually giving you a compile *error*.

You can get a copy of the ANSI C draft (same as the standard AFAIK)
by FREQing ANSI_C.* from 3:711/934.  I don't actually know the 
answer myself, but on looking it up, I would say that that is
implementation-defined, ie a conforming compiler could set the 
above value to "0", "5" or "32767" if it wanted to.

Interestingly I could find nothing that restricts the length you
can specify there, e.g. you could go

int zees = 'ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ';

and I can't see anything that would allow the compiler to treat that
as an error.

The reference that I looked at was ISO 6.1.3.4, which says "The value
of an integer character constant containing more than one character,
or containing ... is implementation-defined".  BFN.  Paul.
