Description

In 0.printf.cpp test the rw_putenv() is used to define variable to null and to undefine variable.

---------------
1. rw_putenv ("NULL="); // define to null (empty string)
2. rw_putenv ("UNSET"); // undefine if defined
---------------

But on MSVC putenv() could not define variable to null, so:
1. rw_putenv ("NULL="); undefines the NULL variable instead defining it to null;
2. rw_putenv ("UNSET"); does nothing instead of undefining variable
