151# 2) In general, libtool expects an argument such as `--tag=CXX' when
152# using the C++ compiler, because that will enable the settings
153# detected when C++ support was being configured.  However, when no
154# such flag is given in the command line, libtool attempts to figure
155# it out by matching the compiler name in each configuration section
156# against a prefix of the command line.  The problem is that, if the
157# compiler name and its initial flags stored in the libtool
158# configuration file don't match those in the command line, libtool
159# can't decide which configuration to use, and it gives up.  The
160# correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe
161# CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to
162# attempt to infer which configuration to use.
163#
164# We have to put --tag disable-shared after --tag CXX lest things
165# CXX undo the affect of disable-shared.

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