antcall at top level causes infinite loop

           Summary: antcall at top level causes infinite loop
           Product: Ant
           Version: 1.1
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Core tasks
        AssignedTo: dev@ant.apache.org
        ReportedBy: gus.heck@olin.edu


A brief search didn't turn up any bugs with "infinite" and "loop" that seemed to
relate to antcall... I havn't looked into the code to see why this happens, but
it seems that antcall is calling the entire buildfile again, to look for the
target named foo. In doing so I suspect it is required to process all top level
information, including itself creating the loop. 

This file: 

<project name="test">
  <antcall target="foo"/>
  <target name="foo">
    <echo>Foo called</echo>
  </target>
</project>

Causes this infinite loop:

gus@draco projects]$ ant -v -f test.xml

(repeats infinitely)

I am a little supprised this hasn't poped up before, but I ran into it when I
tried to devise a build that checked to see if libs were in the right place and
if not, attempt to get them from likely locations before proceeding. I was
antcalling a target that had an unless"foolib.exists" (set or not set by
available).  I think one can workaround this by putting all the toplevel stuff
in an explicit init target, but if all tasks are to work on the top level, it
would seem that antcall needs to be fixed.
