2cae2b7d30 VarAdd() already does the debug printing, so Var_Set() only needs to do it
in the case the var already exists.

7d81571413 - match_var: do not address memory at invalid address (`len' can be greater
than strlen(var) + 1)
- ReadMakeFile: prevent `fname' memory leak
- ReadMakeFile: prevent double free (caused by double fclose) --
ParsePopInput() closes input file

671adc85da Var_SubstOnly() is only used to subsitute a variable from the global
context (and only in one place to substitute the .for variable). Therefor
there is no need to pass the context as a parameter.

103823e628 Make make a little bit more POSIXish with regard to option parsing:
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.

02c3270da1 Split Var_Subst() into two functions: Var_SubstOnly() which substitutes
only one variable and Var_Subst() which substitutes all. Split out the
test whether a variable should not be expanded into match_var().
Make access to the input string consistently using str[]. Remove two
unused functions: Var_GetTail() and Var_GetHead().

352a63dee8 Introduce a new pseudo-target .EXPORTVAR which allows to put a
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.
