 118 # 1) Need to explicitly set LTCXXCOMPILE so that AM_CXXFLAGS is

 121
 122 # 2) In general, libtool expects an argument such as `--tag=CXX' when
 123 # using the C++ compiler, because that will enable the settings
 124 # detected when C++ support was being configured.  However, when no
 125 # such flag is given in the command line, libtool attempts to figure
 126 # it out by matching the compiler name in each configuration section
 127 # against a prefix of the command line.  The problem is that, if the
 128 # compiler name and its initial flags stored in the libtool
 129 # configuration file don't match those in the command line, libtool
 130 # can't decide which configuration to use, and it gives up.  The
 131 # correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe
 132 # CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to
 133 # attempt to infer which configuration to use.
 134 #
 135 # We have to put --tag disable-shared after --tag CXX lest things
 136 # CXX undo the affect of disable-shared.

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