IBM R/6000 C-compiler question

[Knobi der Rechnerschrat]

Hello,

  as the IBM R/6000 machines seem to be a valid topic on this list,
I would like to ask two questions:

  a) does anybody, who had that machine at hands, know whether the C
     compiler supports ansi-style argument declarations for procedures?

  b) which version of gl (in time and IRIX release numbers) did IBM purchase
     from SGI?


Thanks in advance
