159# Libtool notes
160
161# 1) In general, libtool expects an argument such as `--tag=CXX' when
162# using the C++ compiler, because that will enable the settings
163# detected when C++ support was being configured.  However, when no
164# such flag is given in the command line, libtool attempts to figure
165# it out by matching the compiler name in each configuration section
166# against a prefix of the command line.  The problem is that, if the
167# compiler name and its initial flags stored in the libtool
168# configuration file don't match those in the command line, libtool
169# can't decide which configuration to use, and it gives up.  The
170# correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe
171# CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to
172# attempt to infer which configuration to use.
173#
174# The second tag argument, `--tag disable-shared` means that libtool
175# only compiles each source once, for static objects. In actuality,
176# glibcxx_lt_pic_flag and glibcxx_compiler_shared_flag are added to
177# the libtool command that is used create the object, which is
178# suitable for shared libraries.  The `--tag disable-shared` must be
179# placed after --tag CXX lest things CXX undo the affect of
180# disable-shared.
181
182# 2) Need to explicitly set LTCXXCOMPILE so that AM_CXXFLAGS is
183# last. (That way, things like -O2 passed down from the toplevel can
184# be overridden by --enable-debug.)
185LTCXXCOMPILE = \
186	$(LIBTOOL) --tag CXX --tag disable-shared \

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