200# last. (That way, things like -O2 passed down from the toplevel can
201# be overridden by --enable-debug.)
202
203# 2) In general, libtool expects an argument such as `--tag=CXX' when
204# using the C++ compiler, because that will enable the settings
205# detected when C++ support was being configured.  However, when no
206# such flag is given in the command line, libtool attempts to figure
207# it out by matching the compiler name in each configuration section
208# against a prefix of the command line.  The problem is that, if the
209# compiler name and its initial flags stored in the libtool
210# configuration file don't match those in the command line, libtool
211# can't decide which configuration to use, and it gives up.  The
212# correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe
213# CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to
214# attempt to infer which configuration to use
215LTCXXCOMPILE = $(LIBTOOL) --tag CXX --mode=compile $(CXX) $(INCLUDES) \

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