Dick Johnson,
earlier in the discussion there was a post of the 'incompatabilities'
that were noted and one of the replies to that listed several c99 tools
available to do the same job with the c99 syntax, so there are at least
some cases where things are done the gcc-only way instead of the c99 way.
nobody is suggesting that the kernel loose functionality to achieve
portability, the suggestion was mearly to be portable where possible and
clearly mark the places where gcc-isms are used and why.
