However, this modification has been applied only to + expand\_smacro and not to smacro\_define: as a consequence expansion + looks in outer contexts, but \code{\%ifdef} won't look in outer contexts. + + This behaviour is needed because we don't want nested contexts to + act on already defined local macros. Example: +\begin{lstlisting} +%define %$arg1 [esp+4] +test eax,eax +if nz + mov eax,%$arg1 +endif +\end{lstlisting} + In this example the "if" mmacro enters into the "if" context, so \%\$arg1 + is not valid anymore inside "if".
