[Bug-dejagnu] 1.4.2 cmd-line

[Wolfgang Pichler]

please re-insert some sort of THIS code (cowardly stolen from some older
runtest.exp) into runtest.exp of 1.4.2 and onwards if missing.

otherwise dejagnu's 'make check' won't work :-)
AND MORE BAD : many others seem to rely on this code to work ...

        "[A-Z]*=*" { # process makefile style args like CC=gcc, etc...
            if [regexp "^(\[A-Z_\]+)=(.*)$" $option junk var val] {
                set $var $val
                verbose "$var is now $val"
                append makevars "set $var $val;" ;# FIXME: Used
anywhere?
                unset junk var val
            } else {
                send_error "Illegal variable specification:\n"
                send_error "$option\n"
            }
            continue
        }
