    00133 # it out by matching the compiler name in each configuration section
    00134 # against a prefix of the command line.  The problem is that, if the
    00135 # compiler name and its initial flags stored in the libtool
    00136 # configuration file don't match those in the command line, libtool
    00137 # can't decide which configuration to use, and it gives up.  The
    00138 # correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe
    00139 # CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to

    00146 # be used since this would add -lstdc++ to the link line which of
    00147 # course is problematic at this point.  So, we get the top-level
