I did this as a part of preparing the testsuite to cope with the
(possible) gnu11 default. But I think it's a reasonable cleanup
on its own. With gnu11, we'd start to warn about defaulting to
int, missing function declarations, and functions without return
type. I added -fgnu89-inline when a test relies on a gnu89 inline
semantics, and -std=gnu89 if a test relies on gnu89 standard.
I have patches that cover the rest of C testsuite, but let's do this
piecewise.
Tested on x86_64-linux: vanilla results == results with this patch ==
results with this patch and gnu11 as a default.
Does this approach make sense?
