  89
  90 # 2) In general, libtool expects an argument such as `--tag=CXX' when
  91 # using the C++ compiler, because that will enable the settings
  92 # detected when C++ support was being configured.  However, when no
  93 # such flag is given in the command line, libtool attempts to figure
  94 # it out by matching the compiler name in each configuration section
  95 # against a prefix of the command line.  The problem is that, if the
  96 # compiler name and its initial flags stored in the libtool
  97 # configuration file don't match those in the command line, libtool
  98 # can't decide which configuration to use, and it gives up.  The
  99 # correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe
 100 # CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to
 101 # attempt to infer which configuration to use.
 102 # We have to put --tag disable-shared after --tag CXX lest things
 103 # CXX undo the affect of disable-shared.

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