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

 265 # the rules automake generates would be used.  We cannot allow g++ to
 266 # be used since this would add -lstdc++ to the link line which of
 267 # course is problematic at this point.  So, we get the top-level
