commit b3f34caa4a4b9ff6862f3b4f1d45560ea4ffee5f
Author: Peter Rosin <address@hidden>
Date:   Mon Feb 13 21:21:48 2012 +0100

    tests: increase coverage for depcomp tests
    
    On platforms requiring that no undefined symbols exist in order
    to build shared libraries (e.g. Windows DLLs), you have to
    explicitly declare that the libtool library you are building
    does not actually have any undefined symbols, for libtool to
    even try to build it as a shared library.  Without that
    explicit declaration, libtool falls back to a static library
    only, regardless of any --enable-shared flags etc.
    
    tests/depcomp.sh (Makefile.am): Add -no-undefined if a libtool
    library (.la) is built.
    (src/Makefile.am): Likewise.
