of the .SHELL target. Formerly it used to select the shell with the
longest common trailing substring, so that bash would select sh, but pocsh
would select csh. Now an exact match is required so that specifying bash
without also giving a path and the other keywords will give an error.

pointers, because otherwise gcc won't let us initialize the fields with
constant strings, and one without the const, because we need to work
with the structure.

so change that place.
rid of a lot of uneccesary casts and temporary variables that have just
obfuscated the code. This also let's us implement a couple of the one-

simplify life once we start to throw consts on the code.
uses the brk_string function to parse the line. That function uses static
storage for both the expanded string and the returned argv[] vector.
The JobParseShell function simply stored away pointers into this static
storage. On the next use of something like ${FOO:O} this storage would
get overwritten with fatal results.
This also allows us to make the shells[] array const bringing us one step
further in making make WARNS=4 ready.

of submakes spawned during processing.
We create a fifo and stuff one character into it for each job we are
allowed to run. The name of the fifo is passed to child processes
in the MAKE_JOBS_FIFO environment variable.
A make which finds this variable on startup will open the fifo and
only spawn jobs when it managed to read a token from the fifo.
When the job completes a token is writen back to the fifo.
Slave make processes get one token for free: the one their parent
make got in order to run them. This makes the make processes
themselves invisible in the process counts.
The net effect is that "make -j 12 -s buildworld" will start at
most 12 jobs at the same time, instead of as previously up to
65 jobs would get started.
from the beginning). Make used to handle all its interrupt-time stuff
directly from the signal handler, including calls to printf, accessing
global data and so on. This is of course wrong and could provoke a core
dump when interrupting make. Just set a flag in the signal handler and
do everything else from the main thread.
