takes place in the child process in a function ProcExec(). Make sure,
that the child does not call malloc() or other potential dangerous
functions (there are still calls to Punt() in the error case that
should go away). Allocate the argv string via malloc to overcome
the non-constness bug of the execvp prototype. Change the handling of
shell meta-characters and move the builtin list near the list of shell
builtins. Both of these lists should actuall be configurable by the .SHELL
target since they depend on the shell used.

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.

on every line that starts with a dot use a minimal perfect hash
function and a single strcmp() on the first word after the dot
to find out whether it is really a directive call and, if yes, which
one. Then directly dispatch to a handler function for that directive
(or fall through to the dependency handling code). This makes the
directive parse a little bit more strict about the syntax: the directive
word must be followed by a character that is not alphanumerical and not
an underline (making .undefFOO illegal); .endif and .else can only be
followed by comments.

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.

proceedes to the begin until either the start of the suffix is hit

match too and replacing the Lst_Find calls with LST_FOREACH loops
