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

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