171# Libtool notes
172
173# 1) In general, libtool expects an argument such as `--tag=CXX' when
174# using the C++ compiler, because that will enable the settings
175# detected when C++ support was being configured.  However, when no
176# such flag is given in the command line, libtool attempts to figure
177# it out by matching the compiler name in each configuration section
178# against a prefix of the command line.  The problem is that, if the
179# compiler name and its initial flags stored in the libtool
180# configuration file don't match those in the command line, libtool
181# can't decide which configuration to use, and it gives up.  The
182# correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe
183# CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to
184# attempt to infer which configuration to use.
185# 
186# The second tag argument, `--tag disable-shared` means that libtool
187# only compiles each source once, for static objects. In actuality,
188# glibcxx_lt_pic_flag and glibcxx_compiler_shared_flag are added to
189# the libtool command that is used create the object, which is
190# suitable for shared libraries.  The `--tag disable-shared` must be
191# placed after --tag CXX lest things CXX undo the affect of
192# disable-shared.
193
194# 2) Need to explicitly set LTCXXCOMPILE so that EXTRA_CXX_FLAGS is
195# last. (That way, things like -O2 passed down from the toplevel can
196# be overridden by --enable-debug.)

204
205# 3) We'd have a problem when building the shared libstdc++ object if
206# the rules automake generates would be used.  We cannot allow g++ to
207# be used since this would add -lstdc++ to the link line which of
208# course is problematic at this point.  So, we get the top-level
209# directory to configure libstdc++-v3 to use gcc as the C++
210# compilation driver.
