commit 032d3cc9c17b51649153f51c50d1586774799cbd
Author: Peter Rosin <address@hidden>
Date:   Wed Mar 18 19:52:27 2009 +0100

    Don't settle for any dumpbin/link program as name lister.
    
    * libltdl/m4/libtool.m4 (LT_PATH_NM): When locating dumpbin or
    link -dump, check if they appear to really be capable of name
    listing, in order to eliminate e.g. link from coreutils. This
    makes the name lister decision fall back on nm as the default if
    no acceptable candidate is found, which mainly happens on
    (arguably broken) cross compiles.
    * NEWS: Update
    * THANKS: Update

   - Link tests are guarded by cache variables so they can be avoided for
     bootstrapping purposes (e.g., when link tests are not possible).
   - Argument mangling of execute mode has been improved (i.e., lessened).
+  - Fix 2.1b regression that caused nm to not be the default name lister.
+    The regression affected mainly (arguably broken) cross compiles.
