163# Libtool notes
164
165# 1) In general, libtool expects an argument such as `--tag=CXX' when
166# using the C++ compiler, because that will enable the settings
167# detected when C++ support was being configured.  However, when no
168# such flag is given in the command line, libtool attempts to figure
169# it out by matching the compiler name in each configuration section
170# against a prefix of the command line.  The problem is that, if the
171# compiler name and its initial flags stored in the libtool
172# configuration file don't match those in the command line, libtool
173# can't decide which configuration to use, and it gives up.  The
174# correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe
175# CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to
176# attempt to infer which configuration to use.
177#
178# The second tag argument, `--tag disable-shared` means that libtool
179# only compiles each source once, for static objects. In actuality,
180# glibcxx_lt_pic_flag and glibcxx_compiler_shared_flag are added to
181# the libtool command that is used create the object, which is
182# suitable for shared libraries.  The `--tag disable-shared` must be
183# placed after --tag CXX lest things CXX undo the affect of
184# disable-shared.
185
186# 2) Need to explicitly set LTCXXCOMPILE so that EXTRA_CXX_FLAGS is
187# last. (That way, things like -O2 passed down from the toplevel can
188# be overridden by --enable-debug.)

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