[PATCH 0/6] {master} restore C90 compliance

[Akim Demaille]

This was done in 2.7, but master added its own C99 changes.  I'd
be happy to revert some of these changes in the future, but there
were also some //-comments in the generated parsers, which there
is no reason to introduce.

Plus some other minor stylistic improvements.

Akim Demaille (6):
  closure, gram: add missing const
  graph: minor simplification
  maint: restore ANSI 89 compliance
  regen
  syncline: one line is enough
  regen
