mode, use the ignErr template for the command as shell doesn't like an empty
construct of the form { } || <something>. Fixes build breakage on cats
distrib where a command ends up expanding to nothing.
Its not posix compliant and serves very little purpose.
With this change compat and jobs modes are consistent wrt how
they treat each line of a script.
Add support for the '+' command line prefix as required by posix.
Lines prefixed with '+' are executed even when -n is given.
[Actually posix says they should also be done for -q and -t]

Instead of adding MAKE_BOOTSTRAP for hosted environments, i.e., when
you want things simple, instead add MAKE_NATIVE to get those hugely
important features like __RCSID().
It's now possible to build make on some hosts with: cc *.c */*.c
Using -e in sh/ksh to stop on error doesn't work with grouped commands. At
least for any SUSE compliant sh(1). Instead, extend the Shell struct and add
errOut which provides a template to use to check error status from commands.
executed the make job with sigprocmask(SIG_BLOCK) in effect for a
number of signals including SIGCHLD. This caused recursive submakes
of the make process in question not to receive SIGCHLDs when their
jobs exited. This was a second, independent cause of bin/18895 in
addition to the race condition already fixed. Fixed by unblocking all
signals before executing the job.
seconds if a SIGCHLD arrived while make was not blocked in poll(),
by making the SIGCHLD handler write to a pipe included in the poll.
Avoided the need to implement a duplicate fix for the USE_SELECT case
by emulating poll() in terms of select() when USE_SELECT is defined.
Fixes bin/18895.
while setting up a child process. This prevents the major sources of
list inconsistencies that may result from doing list manipulations
from a signal handler.
XXX - all Lst_*() operations are at risk; look for ways to avoid touching
so much global state from the signal handlers.
- don't block the signal we're about to send to ourselves to
take the default action for
- restore the signal handler for the current signal
- remove duplicate sigprocmask() call
As a result, restoring the SIGTSTP handler in JobContinueSig() is no longer
necessary.
make sure that the dir actually exists. In compat mode the corresponding
chdir simply fails and all is well - the issue only arises when playing
tricky games with the value of .CURDIR.

1. make -dx turns on DEBUG_SHELL which causes sh -x to be used where
possible.
2. PrintOnError() is now called when make is stopping due to an error.
This routine reports the curdir and the value of any variables listed
in MAKE_PRINT_VAR_ON_ERROR.
3. Variables set via command line, are propagated to child-makes via
MAKEFLAGS. This behaviour appears to be necessary for POSIX (according
to the GNU folk anyway).
4. Do not reset MAKEFILE when reading ".depend" as this rather eliminates the
usefulness of ${MAKEFILE}.
5. Added ${.newline} as a simple means of being able to include \n in the
result of a :@ loop expansion.
6. Set ${MAKE_VERSION} if defined. Need to come up with a useful value.

- install SIGCONT handler which reestablishes SIGTSTP handler and then calls
JobRestartJobs() to restart all the suspended jobs.
- when SIGTSTP is handled, call JobCatchChildren() so *** Suspended messages
get printed before make stops rather than after.
