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