           Summary: --enable-objc-gc should be automatic
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libobjc
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: ro@gcc.gnu.org
                CC: nicola@gcc.gnu.org, pinskia@gcc.gnu.org


Currently, --enable-objc-gc, which isn't documented in install.texi, is
required
to enable building libobjc_gc.la.  This could (and should) be automatic: either
automatically build boehm-gc if libobjc is enabled or only build libobjc_gc if
boehm-gc is already built.

The fewer necessary configure options, the better.
