I obviously forgot that in C, unlike in Ada, the storage order of arrays is
that of their component type, so you need to look at it when deciding to warn.
The bug reporter also complains about a bogus warning on the assignment of a
pointer returned by alloca or malloc, so this also fixes that.

Quite some TEXI tables do miss table header.
The patch adds that. Pushed to master as obvious.

Hello.
I'll need to parse output of tm.texi when converted to Sphinx for the future

Hi!
The following testcase ICEs, because gimple_call_arg_ptr (..., 0)

Hi José,
Patch tested only on x86_64-pc-linux-gnu.
Also tested on darwin20. The patch is OK for me provided the updated
PR94331.c test file replaces the original one.
Since the PRs are about wrong code, I think the patch should be
backported to at least GCC11 (applied and regtested OK).

The current implementation as an array of chars is indeed a bit awkward so
this reimplements it as a function taking and returning an int.
