[Giulio Orsero]

Package: busybox
Version: 0.52
Severity: normal

problem:
"echo $$"  clutters following "echoed" vars.

system:
linux, glibc-2.1.2-11, 2.2.19
added 
#define ASH_BBAPPS_AS_BUILTINS
to Config.h to make ash compile as suggested on the list by Aaron

Enter 'help' for a list of built-in commands.
 
$ myvar=somevalue
$ echo $myvar
somevalue
$ echo $$         <===== (does not echo anything)
$ echo $myvar
