354 # using the C++ compiler, because that will enable the settings
355 # detected when C++ support was being configured. However, when no
356 # such flag is given in the command line, libtool attempts to figure
357 # it out by matching the compiler name in each configuration section
358 # against a prefix of the command line. The problem is that, if the
359 # compiler name and its initial flags stored in the libtool
360 # configuration file don't match those in the command line, libtool
361 # can't decide which configuration to use, and it gives up. The
362 # correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe
363 # CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to
