[jamming] locals not local

[Alen Ladavac]

Hi Craig,

The syntax for "on" is: "<var> on <target> = <expression> ;". Notice
that the var's value is set on a _target_ not on another var. Perhaps
you ment to do something like this?:

rule A
{
  local here = sometarget;
  x on $(here) = in-a ;
}

Which effectively sets the value of "x" on a pseudo-target named
"sometarget".

etc...

Btw, for pseudo-targets targets, I find it simpler to use a variable
that includes a target's name than to set a variable on the target.
E.g. instead of

FAKED on $(project) = 1 ;

I'd do

$(project)-FAKED = 1 ;

Which is then easily read by $($(project)-FAKED) . The "on" syntax is
more suitable when used in actions. But it's a matter of taste.

HTH,
Alen
