[neil@gcc.gnu.org]

Synopsis: gcc hangs on C compile with multiple "-I-"

Responsible-Changed-From-To: unassigned->neil
Responsible-Changed-By: neil
Responsible-Changed-When: Tue May 21 11:57:28 2002
Responsible-Changed-Why:
    Mine.
State-Changed-From-To: open->analyzed
State-Changed-By: neil
State-Changed-When: Tue May 21 11:57:28 2002
State-Changed-Why:
    Confirmed.  It hasn't actually hanged, the preprocessor
    ignores the rest of the command line, missing the input
    file, and so waits for input from stdin.  ^D will return
    to the prompt.
    
    Fix coming up.
