> #pragma are considered statements.

This can't be entirely true, since #pragma can be used where statements cannot
(outside of functions), and #pragma STDC certainly isn't considered a
statement.
At least, this implementation-defined behaviour has to be documented (hasn't
it?), and I couldn't find mention of it in the documentation. Would you
recommend filing a separate documentation bug report?
