asterisk users - Oct 2006 - AEL2 #include madness in Asterisk 1.4 - Murf?

Asterisk 1.4 beta2.
 
My top level /etc/asterisk/extensions.ael has the following two lines:
 
#include "include/syst/extensions.ael"
#include "include/btck/extensions.ael"

Here is the console output on Asterisk load.

pbx_ael.so => (Asterisk Extension Language Compiler)
 
Here's the context from /etc/asterisk/include/syst/extensions.ael, that
contains lines 157 that the parser is complaining about:
 
   148  context syst_Route {
   149
   150      _[*0123456789]. => {
   151          NoOp(*** Originated call ${CALLERID} -> ${EXTEN});
   152          Set(TMP=${CALLERID(number)});
   153          &SysLogger(This is a test message);
   154          &FastAGIConnectGet(CALLERID);
   155          ChanIsAvail(SIP/${EXTEN});
   156          if ("${AVAILCHAN}" = "") {
   157              goto remote;
   158          } else {
   159              goto local;
   160          }
   161          remote:
   162              NoOp(REMOTE);
   163              Set(PATH=${DUNDILOOKUP(3254103,DUNDIRegistr)});
   164              //Set(PATH=${DUNDILOOKUP(${EXTEN},DUNDIRegistr)});
   165              Dial(${PATH});
   166              Hangup();
   167          local:
   168              NoOp(LOCAL);
   169              Dial(SIP/${EXTEN});
   170              Hangup();
   171
   172      }
   173  }
 
As you can quite clearly see, labels 'remote' and 'local' DO
exist in the syst_Route context.
 
Now, if I switcheroo the two includes around in the top level
/etc/asterisk/extensions.ael, to:
 
#include "include/btck/extensions.ael"
#include "include/syst/extensions.ael"

and reload Asterisk, I get:

pbx_ael.so => (Asterisk Extension Language Compiler)

There are no errors about nonexistent labels in the syst_Route extension. I
would not have thought that #include order made any difference, since all we are
doing is pulling a bunch of contexts into a global context space.
 
Anyone? Mr Murpy, care to take a shot at it?  :)
 
Doug.

I cannot reproduce the problems, given just the one context. 
There is something magical about your data, that the code trips over it,
and
to find the bugs, I will need your files! Is this possible?

As to order, you are correct, it should not make a difference what order
the
files are included in the data.

I did note that in the above output, you got the error messages:

[Oct  4 15:57:28] WARNING[1202]: pbx.c:6194 ast_context_verify_includes:
Context 'syst_PSTNStart' tries includes nonexistent context
'syst_AppACDQueue'
[Oct  4 15:57:28] WARNING[1202]: pbx.c:6194 ast_context_verify_includes:
Context 'btck_CallStart' tries includes nonexistent context
'syst_ACD'

These messages do not come from the AEL compiler, but rather, are
complaints from the bowels of the asterisk engine: somewhere, it's not
finding some included contexts... which may mean yet one more bug in the
AEL code: why didn't AEL make note of it first?
