to use sret or inreg on the function. It is equally illegal to use noreturn
or nounwind on a parameter; they only go with the function. This patch
enforces these rules.

that cannot be suppressed and cannot be redirected:
they are dumped in the current working directory.
When running the testsuite this means that these
files do not end up in the Output directory.  The
best solution I could find is to change directory
into Output before running tests.

to /dev/null - this cannot always be arranged.

This requires special treatment, as the include name is lexed
as multiple tokens, which require reassembly before processing.
