* 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).

/*
|
|
* This program was originally written long ago, originally for a non
|
|
* BSD-like OS without mkstemp(). It's been modified over the years
|
|
* to use mkstemp() rather than the original O_CREAT|O_EXCL/fstat/lstat
|
|
* etc style hacks.
|
|
* A cleanup, misc options and mkdtemp() calls were added to try and work
|
|
* more like the OpenBSD version - which was first to publish the interface.
