undo, the right place for this is compat_defs.h

Provide a backward-compatible conditional define of O_CLOEXEC
for those systems which lack it, since these files are used in
tools builds.

make more descriptors that we open as close-on-exec

don't depend on expandtc to open the database or not.

PR/45989: Martin Husemann: lint invocation does include -w only on i386

- turn lint -w for all the platforms after fixing the lint warnings.
- add _DIAGASSERTS() for casts that would assign values to types that
would not fit.
- change types, add casts
- change into ansii prototypes
- turn on _DIAGNOSTIC for libc (during current, to be eliminated for release
builds)

close on exec fixes:
- open + fcntl -> open O_CLOEXEC
- configuration database file descriptors that can stay open are now opened
fopen(db, "re")

Don't define weak aliases in the SMALL case. They conflict with the real
function name since SMALL doesn't use the normal rename logic.

Add csetexpandtc()

missed check for malloc() returning NULL

Add coverity annotations.

Coveriry CID 509: Avoid NULL pointer deref.

Add -DSMALL so that this can be used in libhack.

Ansify and add change db_name vector from char ** to const char * const *

Overhaul how `build.sh tools' are used:

* 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/com

Overhaul how `build.sh tools' are used:

* 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).

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22280, verified by myself.

Avoid cgetcap &co prototypes conflicting with those provided by the host.
With this change we can cross-compile on FreeBSD 4.x.

Include "sys/param.h" and use "MATHPATHLEN" instead of "_POSIX_PATH_MAX"
to fix build problem.

Detect if line length exceeds buffer capacities.

avoid an underrun in "buf". noted by dean@huxley.org in PR#13292
