Make "set -e" once again provide the behavior documented in the man page,
...
which was unnecessarily changed in revision 1.50 while fixing other bugs.
That is, exit the shell if the last command in a || or && compound statement
is not short-circuited, and exits with a false status. I.e., the following
will cause the shell to exit:
set -e
false || false
While this is not the prescribed behavior in SUSv3, it is what our man page
documents, and it is what all of the following implementations do:
NetBSD /bin/ksh (pdksh)
bash
zsh
Solaris 9 /bin/sh
Solaris 9 /usr/xpg4/bin/sh
Solaris 9 /usr/bin/ksh
Tru64 /bin/sh
HP/UX 11 /bin/sh
The "standard" seems to be wrong in this instance.

Put a syntax.c under CVS instead of building if with the mksyntax program.
...
Kill mksyntax.c - no longer possible to get the 'wrong sort of chars'.
/bin/sh now has no helper binaries.
syntax.c uses C99 initialisers, run time initialisation could be used
for systems where the compiler doesn't support them.
I've used some #defines to help make this possible - but writing the code
starts making it rather messy.

Rework how MAKEVERBOSE operates:

* Don't bother prefixing commands with a line of ${_MKCMD}\

_MKMSG_FOO Run _MKMSG 'foo'
_MKTARGET_FOO Run _MKMSG_FOO ${.TARGET}
