 174 # Libtool notes
 175
 176 # 1) In general, libtool expects an argument such as `--tag=CXX' when
 177 # using the C++ compiler, because that will enable the settings
 178 # detected when C++ support was being configured.  However, when no
 179 # such flag is given in the command line, libtool attempts to figure
 180 # it out by matching the compiler name in each configuration section
 181 # against a prefix of the command line.  The problem is that, if the
 182 # compiler name and its initial flags stored in the libtool
 183 # configuration file don't match those in the command line, libtool
 184 # can't decide which configuration to use, and it gives up.  The
 185 # correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe
 186 # CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to
 187 # attempt to infer which configuration to use.
 188 #
 189 # The second tag argument, `--tag disable-shared` means that libtool
 190 # only compiles each source once, for static objects. In actuality,
 191 # glibcxx_lt_pic_flag and glibcxx_compiler_shared_flag are added to
 192 # the libtool command that is used create the object, which is
 193 # suitable for shared libraries.  The `--tag disable-shared` must be
 194 # placed after --tag CXX lest things CXX undo the affect of
 195 # disable-shared.
 196
 197 # 2) Need to explicitly set LTCXXCOMPILE so that EXTRA_CXX_FLAGS is
 198 # last. (That way, things like -O2 passed down from the toplevel can
 199 # be overridden by --enable-debug.)

 208 # 3) We'd have a problem when building the shared libstdc++ object if
 209 # the rules automake generates would be used.  We cannot allow g++ to
 210 # be used since this would add -lstdc++ to the link line which of
 211 # course is problematic at this point.  So, we get the top-level
