Version 4.3.1+dbg-1.5 (2020-03-15) Ron Frankel

Rebase code on GNU Make 4.3.

This was made possible by Thomas Kupper (boretom) who did all the heavy lifting \ 
while rocky looked on in amazement.

Thomas also added OS/X CI testing, and tested on the BSD-ish platforms.

With this release, we've started redoing the texinfo documentation in sphinx and \ 
put on readthedocs. Since sphinx supports output into LaTeX, TeXinfo, pdf, epub, \ 
and info as well as HTML, the TeXinfo document will be removed when the sphinx \ 
documentation is more stable. I expect the in next release to work on this.

Similarly, you'll see that README.md has been redone and includes screencasts. \ 
The install docs have also been corrected and expanded.
New and Changed Features

    --search parent -- I really like this one.
    --tasks -- the definition of a "tasks" has been simplified. Now, \ 
it is simply a target that has a description comment (#:) before it. After many \ 
years of using this myself, I highly encourage people to start using description \ 
comments more. Output from running remake --tasks is nicer because we use spaces \ 
to align columns rather than tabs.

Debugger Changes

    Commands with file expansion now use glob(), not word_expand() (Thomas did \ 
this too). Previously source used to POSIX.1-2008 wordexp(), but this is not \ 
available on BSD-ish systems. glob() is more general, and GNU make ships with \ 
its own glob() function when none is provided in the underlying OS library.
    load command added eval command removed. eval never worked and it attempted \ 
to be the same thing as load; load is the gdb name.
    $(debugger) function fixed. This function gave an virtual memory exhausted \ 
on exit. This has been fixed. The required parameter for this function, a tag \ 
name, is now shown on entry
    info tasks has been added. It is basically the same thing as remake --tasks
    Description lines are now shown on in info targets and list commands
    The debugger now disallows any "running" command inside \ 
post-mortem debugging
    Help as shown inside the debugger has been greatly expanded and more closely \ 
matches the sphinx docs. We now show in help text the short command name and any \ 
aliases attached to the command
