Funny you should mention that, as that feature has come up recently in mailing list discussions. We have not seen an actual proposal for adopting it yet, but features similar semantics are being discussed as a possible idea (no promises).

FWIW, I don't think it would wind up being spelled with attribute syntax because we would likely want programmers to have a guarantee that the cleanup will happen (and attributes can be ignored by the implementation).

Hopefully it'd at least be syntactically similar, so we can have an

  #ifdef __STDC_CLEANUP__
  #define my_cleanup(func) stdc_cleanup(func)
  #else
  #define my_cleanup(func) __attribute__((cleanup(func)))
  #endif

i.e. it would require that it at least goes in the same places as an attribute.

I believe the last proposal was in 2008 (ignore the try..finally stuff here): http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1298.pdf

So I guess it needs someone to take that and update it, also to pull up a full list of current Linux software which is using this feature (which as I say these days is a surprising amount).
