Since 2003 bmake switched to a date based version (first was 20030714)
which generally represents the date it was last merged with NetBSD's
make. Since then, NetBSD's make is imported within a week of any
interesting changes, so that bmake tracks it very closely.

./configure; make; make install
This will *not* work on Darwin or any other system with a case
insensitive filesystem. It depends on a generated ``makefile`` which
is disabled by default on Darwin.
To make much use of bmake you will need the bsd.*.mk macros or my
portable *.mk macros which are included with bmake since 20121212
and separately available from
http://www.crufty.net/ftp/pub/sjg/mk.tar.gz
which will be links to the latest versions.

Porting
=======
If you encounter a system that bmake does not build or work on *out of
the box*, I welcome patches.
Even a report of unit tests which fail is appreciated.
If you can provide access to a suitable machine - even better.

* The need for the caching of whole directories is brought about by the

* 1) just use stat to test for a file's existence. As mentioned above,

* 2) use readdir() and company to search the directories, keeping them

* parallelism available as each directory open would take another file
* descriptor out of play for handling I/O for another job. Given that
* it is only recently (as of 1993 or earlier) that UNIX OS's have taken
* to allowing more than 20 or 32 file descriptors for a process, this

* 2) use readdir() to search the directories, keeping them open between
* checks. Around 1993 or earlier, this didn't slow down the process too
* much, but it consumed one file descriptor per open directory, which
* was critical on the then-current operating systems, as many limited
* the number of open file descriptors to 20 or 32.

2024-01-05 Simon J Gerraty <sjg@beast.crufty.net>
* install-mk (MK_VERSION): 20240105
* dirdeps.mk: for MAKE_VERSION 20240105 we do not have the same
limits on command line length, so skip export of lists to env.
2023-12-24 Simon J Gerraty <sjg@beast.crufty.net>
* man.mk: add logic for staging man pages
2023-11-28 Simon J Gerraty <sjg@beast.crufty.net>
* jobs.mk: avoid C suffix in JOB_MAX_C if factor is floating
point. This keeps JOB_MAX numeric incase another makefile does
comparisons.
2023-11-04 Simon J Gerraty <sjg@beast.crufty.net>
* dpadd.mk: add support for DPLIBS_QUALIFIER_LIST
* gendirdeps.mk: if META_XTRAS is passed to us, add to META_FILES
2023-10-03 Simon J Gerraty <sjg@beast.crufty.net>
* compiler.mk (COMPILER_VERSION): clang at least is into
double digit major versions.
2023-10-02 Simon J Gerraty <sjg@beast.crufty.net>
* install-mk (MK_VERSION): 20231001
* set _CCLINK in init.mk so lib.mk can use it for default SHLIB_LD
* lib.mk (cleanlib): use LD_solink so we remove all the right files.
Use -Wl for -soname since we now default to linking with CC
We should not need SHLIB_LDSTARTFILE or SHLIB_LDENDFILE when linking
with CC.
2023-09-24 Simon J Gerraty <sjg@beast.crufty.net>
* init.mk (QUALIFIED_VAR_LIST): Add SRCS
2023-09-09 Simon J Gerraty <sjg@beast.crufty.net>
* jobs.mk (JOB_MAX): use -jC if we can
