140 # last. (That way, things like -O2 passed down from the toplevel can
141 # be overridden by --enable-debug.)
143 # 2) In general, libtool expects an argument such as `--tag=CXX' when
144 # using the C++ compiler, because that will enable the settings
145 # detected when C++ support was being configured. However, when no
146 # such flag is given in the command line, libtool attempts to figure
147 # it out by matching the compiler name in each configuration section
148 # against a prefix of the command line. The problem is that, if the
149 # compiler name and its initial flags stored in the libtool
150 # configuration file don't match those in the command line, libtool
151 # can't decide which configuration to use, and it gives up. The
152 # correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe
153 # CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to
154 # attempt to infer which configuration to use.
156 # We have to put --tag disable-shared after --tag CXX lest things
157 # CXX undo the affect of disable-shared.

163 # the rules automake generates would be used. We cannot allow g++ to
164 # be used since this would add -lstdc++ to the link line which of
165 # course is problematic at this point. So, we get the top-level
166 # directory to configure libstdc++-v3 to use gcc as the C++
167 # compilation driver.
