gcc/libio/dbz

The dbz package was "liberated" from C News.
It is included with the GNU libio because it provides
a fairly good work-out for a stdio implementation.
The Makefile.in, configure.in, and stdio.h have been
set up to test libio.

This is the new, improved, lemon-freshened :-) dbz.

Just "make" will get you dbz.o and the dbz program.  "make r" runs an
extensive set of regression tests; most of the mysterious oddments lying
around here are to do with that.  "make rclean" cleans up after "make r".

You probably want to inspect the #ifdef list early in dbz.c before
compiling, although the defaults should work all right on most systems.

If you are not building this as part of C News, you will need to change
the -I option in FLAGS in the Makefile to "-I.", and delete the DBMLIBS
and RFC lines entirely.  That will break some of the regression tests;
at some point I'll fix this.

If you are using this independently from C News, you probably still want
to look through ../notebook/problems, as some of the portability problems
described in there can affect dbz.
