204 # last. (That way, things like -O2 passed down from the toplevel can
205 # be overridden by --enable-debug.)
207 # 2) In general, libtool expects an argument such as `--tag=CXX' when
208 # using the C++ compiler, because that will enable the settings
209 # detected when C++ support was being configured. However, when no
210 # such flag is given in the command line, libtool attempts to figure
211 # it out by matching the compiler name in each configuration section
212 # against a prefix of the command line. The problem is that, if the
213 # compiler name and its initial flags stored in the libtool
214 # configuration file don't match those in the command line, libtool
215 # can't decide which configuration to use, and it gives up. The
216 # correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe
217 # CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to
218 # attempt to infer which configuration to use

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