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

167
168# 2) In general, libtool expects an argument such as `--tag=CXX' when
169# using the C++ compiler, because that will enable the settings
170# detected when C++ support was being configured.  However, when no
171# such flag is given in the command line, libtool attempts to figure
172# it out by matching the compiler name in each configuration section
173# against a prefix of the command line.  The problem is that, if the
174# compiler name and its initial flags stored in the libtool
175# configuration file don't match those in the command line, libtool
176# can't decide which configuration to use, and it gives up.  The
177# correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe
178# CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to
179# attempt to infer which configuration to use

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