127# 1) Need to explicitly set LTCXXCOMPILE so that AM_CXXFLAGS is

130
131# 2) In general, libtool expects an argument such as `--tag=CXX' when
132# using the C++ compiler, because that will enable the settings
133# detected when C++ support was being configured.  However, when no
134# such flag is given in the command line, libtool attempts to figure
135# it out by matching the compiler name in each configuration section
136# against a prefix of the command line.  The problem is that, if the
137# compiler name and its initial flags stored in the libtool
138# configuration file don't match those in the command line, libtool
139# can't decide which configuration to use, and it gives up.  The
140# correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe
141# CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to
142# attempt to infer which configuration to use
143LTCXXCOMPILE = $(LIBTOOL) --tag CXX --mode=compile $(CXX) $(INCLUDES) \

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