asterisk users - Oct 2009 - What happened to MACRO_EXTEN in AEL macros since 1.6?

Hi!

Since 1.6, when using AEL, macros are implemented using Gosub(). Is 
there workaround to have MACRO_EXTEN also in this case?

regards
Klaus

PS: I know I could use something like

   context fromSip {
     11 => &myMacro(${EXTEN})
   }
   macro myMacro(MACRO_EXTEN) {
   }

but isn't there some workaround to achieve compatibility with 1.4?
