158# Libtool notes
159
160# 1) Need to explicitly set LTCXXCOMPILE so that AM_CXXFLAGS is
161# last. (That way, things like -O2 passed down from the toplevel can
162# be overridden by --enable-debug.)
163
164# 2) In general, libtool expects an argument such as `--tag=CXX' when
165# using the C++ compiler, because that will enable the settings
166# detected when C++ support was being configured.  However, when no
167# such flag is given in the command line, libtool attempts to figure
168# it out by matching the compiler name in each configuration section
169# against a prefix of the command line.  The problem is that, if the
170# compiler name and its initial flags stored in the libtool
171# configuration file don't match those in the command line, libtool
172# can't decide which configuration to use, and it gives up.  The
173# correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe
174# CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to
175# attempt to infer which configuration to use.
176#
177# We have to put --tag disable-shared after --tag CXX lest things
178# CXX undo the affect of disable-shared.

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