Rex Jaeshke has written several articles titled "Pragmania" in the
Journal of C Language Translation.  The articles report the results
of implementors surveyed for the pragmas they support.

This is even better than the clearing-house concept you suggest, since
I can make the decisions rather than someone who doesn't know about my
peculiar environment.  Plus, by seeing other pragmas, I get a good
feel for how people are using pragmas in general.

Since Rex will probably continue to regularly update "Pragmania", I
encourage you to send him description of your pragmas (especially
those really obscene ones).
