 134 # 2) In general, libtool expects an argument such as `--tag=CXX' when
 135 # using the C++ compiler, because that will enable the settings
 136 # detected when C++ support was being configured.  However, when no
 137 # such flag is given in the command line, libtool attempts to figure
 138 # it out by matching the compiler name in each configuration section
 139 # against a prefix of the command line.  The problem is that, if the
 140 # compiler name and its initial flags stored in the libtool
 141 # configuration file don't match those in the command line, libtool
 142 # can't decide which configuration to use, and it gives up.  The
 143 # correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe
 144 # CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to

 157 # course is problematic at this point.  So, we get the top-level
