* Rename "config.h" to "nbtool_config.h" and
HAVE_CONFIG_H to HAVE_NBTOOL_CONFIG_H.
This makes in more obvious in the source when we're using
tools/compat/config.h versus "standard autoconf" config.h
* Consistently move the inclusion of nbtool_config.h to before
<sys/cdefs.h> so that the former can provide __RCSID() (et al),
and there's no need to protect those macros any more.
These changes should make it easier to "tool-ify" a program by adding:
#if HAVE_NBTOOL_CONFIG_H
#include "nbtool_config.h"
#endif
to the top of the source files (for the general case).
1) register variables have been killed, except for the ones in the
generated skeleton (which should probably also be killed soon).
2) __P(())ified prototypes for all functions.
3) new style __RCSID's, and #include <sys/cdefs.h>'s.
4) all warnings generated with WARNS=1 (i.e. all warnings you get from
gcc with -Wall -Wstrict-prototypes -Wmissing-prototypes) have been
fixed, although not always in the best possible way.
in particular on #4, in a couple of places I got "control reaches end
of non-void function" errors, and sadly __dead doesn't seem to really
work, so I inserted a couple of exit() calls in strategic
places. These should be nuked if someone can get __dead to Do The
Right Thing.
There were also a couple of places where "while (foo = bar)" things
cropped up and I didn't do the best conceivable thing, but I usually
did.
These fixes should probably go back to the byacc maintainers.
