Summary:                    AEL parser broken in 1.4 branch
Description: 
Hi!

I use Asterisk 1.4.23 with AEL without problems. Recently I tried 1.4
branch with release SVN-branch-1.4-r178373 but now the AEL parses produces
lots of errors like

[Feb 24 22:44:12] WARNING[21049]: ast_expr2.fl:409 ast_yyerror:
ast_yyerror(): file extensions.ael, line 262, columns 16-16, if expr
'${EXISTS(${MYVARIABLE})}': syntax error: syntax error, unexpected '(',
expecting $end; Input:
${EXISTS(${MYVARIABLE})}

This is the config which causes the error:

context aelTest {
        881 => {
                if (${EXISTS(${MYVARIABLE})}) {
                        Dial(SIP/user1);
                        Verbose(dialstatus=${DIALSTATUS});
                } else {
                        Hangup();
                }
        }
}


It happens with different functions, e.g:

context toSIPPhones2 {
        366 => {
               
HTTPRESPONSE=${CURL(http://www.domain.at/kd/osa.php?num=1)};

declaration expr '${CURL(http://www.domain.at/kd/osa.php?num=1)}': syntax
