have pmake set environment variables

[klp2]

Hi Nick,

On my windows machine i'm a user of your very useful
pmake. On otherplateform, with other make avartar, it
seems to me that when you put parameters on the command
line, these parameters are automatically defined
as environment variables. So the following minor
modification of the apply() method. That's satisfied my
own needs, but i ignore if this modification is really
right.

Regards
Philippe

sub apply
{
 my $self = shift;
 my $method = shift;
 $self->NextPass;
 my @targets = ();
 # print STDERR join(' ',Apply => $method,@_),"\n";
 foreach (@_)
 {
 if (/^(\w+)=(.*)$/)
 {
 #print STDERR "OVERRIDE: $1 = $2\n";
 $self->{Override}{$1} = $2;
 # PHV
 $ENV{$1} = $2;
 # PHV
 }
 else
 {
 push(@targets,$_);
 }
 }
 #
 # This expansion is dubious as it alters the database
 # as a function of current values of Override.
 #
 $self->ExpandTarget; # Process $(VAR) :
 @targets = ($self->{'Targets'}[0])->Name unless (@targets);
 # print STDERR join(' ',Targets => $method,map($_->Name,@targets)),"\n";
 foreach (@targets)
 {
 my $t = $self->{Depend}{$_};
 unless (defined $t)
 {
 print STDERR join(' ',$method,@_),"\n";
 die "Cannot `$method' - no target $_"
 }
 $t->$method();
 }
}

Since other makes don't do this, and there are already ways to set env-vars, there is no reason to do so in this program. Reluctantly closing. (RT ticket also closed)

In fact, GNU make does do this: https://www.gnu.org/software/make/manual/make.html#Environment
