198# 1) Need to explicitly set LTCXXCOMPILE so that AM_CXXFLAGS is
199# last. (That way, things like -O2 passed down from the toplevel can
200# be overridden by --enable-debug.)
201
202# 2) In general, libtool expects an argument such as `--tag=CXX' when
203# using the C++ compiler, because that will enable the settings
204# detected when C++ support was being configured.  However, when no
205# such flag is given in the command line, libtool attempts to figure
206# it out by matching the compiler name in each configuration section
207# against a prefix of the command line.  The problem is that, if the
208# compiler name and its initial flags stored in the libtool
209# configuration file don't match those in the command line, libtool
210# can't decide which configuration to use, and it gives up.  The
211# correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe
212# CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to
213# attempt to infer which configuration to use
214LTCXXCOMPILE = $(LIBTOOL) --tag CXX --mode=compile $(CXX) $(INCLUDES) \
215	       $(AM_CPPFLAGS) $(CPPFLAGS) $(CXXFLAGS) $(AM_CXXFLAGS) 
216
217# 3) We'd have a problem when building the shared libstdc++ object if
218# the rules automake generates would be used.  We cannot allow g++ to
219# be used since this would add -lstdc++ to the link line which of
220# course is problematic at this point.  So, we get the top-level
221# directory to configure libstdc++-v3 to use gcc as the C++
222# compilation driver.
