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

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