Enough users expect the namespace starting with underscore to be safe for symbols. Change our private namespace from __foo__ to __?foo?__. Use %defalias to provide backwards compatiblity (by using %defalias instead of %define, we handle the case properly where the user changes the value.) Add a preprocessor directive: %aliases off ... to disable all smacro aliases and thereby making the namespace clean. Finally, fix infinite recursion when seeing %? or %?? due to paste_tokens(). If we don't paste anything, the expansion is done. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
