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

230 # be used since this would add -lstdc++ to the link line which of
231 # course is problematic at this point. So, we get the top-level
232 # directory to configure libstdc++-v3 to use gcc as the C++
233 # compilation driver.
