 119 # 2) In general, libtool expects an argument such as `--tag=CXX' when
 120 # using the C++ compiler, because that will enable the settings
 121 # detected when C++ support was being configured.  However, when no
 122 # such flag is given in the command line, libtool attempts to figure
 123 # it out by matching the compiler name in each configuration section
 124 # against a prefix of the command line.  The problem is that, if the
 125 # compiler name and its initial flags stored in the libtool
 126 # configuration file don't match those in the command line, libtool
 127 # can't decide which configuration to use, and it gives up.  The
 128 # correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe
 129 # CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to
 130 # attempt to infer which configuration to use

 134 # 3) We'd have a problem when building the shared libstdc++ object if
 135 # the rules automake generates would be used.  We cannot allow g++ to
 136 # be used since this would add -lstdc++ to the link line which of
 137 # course is problematic at this point.  So, we get the top-level
 138 # directory to configure libstdc++-v3 to use gcc as the C++
 139 # compilation driver.
