 232 # Libtool notes
 233
 234 # 1) In general, libtool expects an argument such as `--tag=CXX' when
 235 # using the C++ compiler, because that will enable the settings
 236 # detected when C++ support was being configured.  However, when no
 237 # such flag is given in the command line, libtool attempts to figure
 238 # it out by matching the compiler name in each configuration section
 239 # against a prefix of the command line.  The problem is that, if the
 240 # compiler name and its initial flags stored in the libtool
 241 # configuration file don't match those in the command line, libtool
 242 # can't decide which configuration to use, and it gives up.  The
 243 # correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe
 244 # CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to
 245 # attempt to infer which configuration to use.
 246 #
 247 # The second tag argument, `--tag disable-shared` means that libtool
 248 # only compiles each source once, for static objects. In actuality,
 249 # glibcxx_lt_pic_flag and glibcxx_compiler_shared_flag are added to
 250 # the libtool command that is used create the object, which is
 251 # suitable for shared libraries.  The `--tag disable-shared` must be
 252 # placed after --tag CXX lest things CXX undo the affect of
 253 # disable-shared.
 254
 255 # 2) Need to explicitly set LTCXXCOMPILE so that EXTRA_CXX_FLAGS is
 256 # last. (That way, things like -O2 passed down from the toplevel can
 257 # be overridden by --enable-debug.)
 258 LTCXXCOMPILE = \
 259         $(LIBTOOL) --tag CXX --tag disable-shared \

 264 LTLDFLAGS = $(shell $(SHELL) $(top_srcdir)/../libtool-ldflags $(LDFLAGS))

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