I gave it some thought, at first considering that going lower than GNU89
was possibly not very useful, but given that the changes are very small
in the end (mostly comments formating), I think that you're right. The
cost of reaching this level of portability is basically zero once the
patch is applied so I think it's worth doing it now. However I think I
will indeed squash all the comments patch together as you suggest.

Thank you!
Willy
