To deal with fools^Wpeople trying to keep really old systems alive,
create a proper framework for substitution functions, and make it
possible to deal with the lack of snprintf/vsnprintf in particular.
We can actually test for the options being accepted, rather than try
to test for gcc; this handles differences between gcc versions as well
as compilers with a similar command line set.
- Remove obsolete types like "uint32"; use "uint32_t" consistently.
- Make sure we include <inttypes.h> where needed.
- Header file guards should be FOO_H or SUBDIR_FOO_H; _FOO_H infringes
on the C implementation's namespace and should only be used when
writing libc!
- Change a few "int8_t" back to "char" where appropriate. There are
a lot more places where that should be done, though.
- Clean up the check for getuid/getgid in rdoff/rdlar.h.
actually *use* the resulting configuration file, but it keeps autoconf
from creating an insanely long compiler command line, which can cause
problems all by itself. Eventually we can do:
#ifdef HAVE_CONFIG_H
#include "config.h"
#endif
... to get the same information.
