take everything after -- as either a macro assignment or a target.
Note that make still reorders arguments before --: anything starting
with a dash is considered an option, anything which contains an equal
sign is considered a macro assignment and everything else a target.
This still is not POSIX with regard to the options, but it will probably
not change because it has been make's behaviour for ages.
Add a new function Var_Match() that correctly skips a macro call by just
doing the same as Var_Subst() but without producing output. This will help
making the parser more robust.

make macro into the environment of programs executed by make. This
has approximately the same function as gmake's export directive.
The form of a pseudo target was deliberately choosen to minimize work
for POSIX compatibility (Makefiles are not allowed to use any targets
starting with a dot and consisting only of uppercase letters except those
specified in the standard when they want POSIX compatible behaviour, so
such a Makefile can never contain .EXPORTVAR.)
Change the handling of macros coming from the environment: instead
of asking the environment for each variable we could not find otherwise
put all the environment variables in a special variable environment just
at start up.
This has been tested on the ports cluster by kris.

to the id_print() function.
Use getgrouplist(3) for the case when an user was specified,
and getgroups(2) when no user was given.
That reverts to the expected behaviour and makes it easy to
implement an option later to force using getgrouplist(3).
NGROUPS groups. getgrouplist(3) may put a duplicate group
id into the passed array (it sets [0] and [1] to the value
of the gid argument), but id_print() sorts them out.
Showing the ids of both an user given by an argument to `id',
and the current user, is now handled in a single function.
Displaying the current user's ids was inaccurate because
getgroups(2) had been used. getgroups(2) returns the current
kernel state of a user's groups, which may not always be
correct if /etc/group was recently changed.

than a negative number indicator (eliminates several special cases),

use table-driven abbreviation logic (eliminate duplicate word entries
and special-case abbreviation and plural handling). The result is
shorter, simpler (judging from comments, earlier maintainers didn't
understand the special handling for "negative years"), handles more
cases (e.g., "tu" is now a recognized abbreviation for "tuesday",
"3rd" is now equivalent to "third") and it has 2 fewer shift/reduce

part). Archive handling was broken at least since the move from BSD ar/ranlib
to GNU binutils because of the different archive format. This rewrite fixes
this by making make to carry around the defines for all formats (it supports)
so it can support all of them independent of the actually used one. The
supported formats are: traditional BSD (this seems to come from V7 at least,
short names only and __.SYMDEF), BSD4.4 (long names with #1/ and __.SYMDEF)
and SysV (extra name table and //). The only format not supported are broken
traditional archives where the member names are truncated to 15 characters.
Errors in the archive are not ignored anymore, but cause make to stop with
an error message. The command line option -A causes these errors to become
non-fatal. This is almost compatible with previous usage except for the
error message printed in any case.
