138# Libtool notes
139
140# 1) In general, libtool expects an argument such as `--tag=CXX' when
141# using the C++ compiler, because that will enable the settings
142# detected when C++ support was being configured.  However, when no
143# such flag is given in the command line, libtool attempts to figure
144# it out by matching the compiler name in each configuration section
145# against a prefix of the command line.  The problem is that, if the
146# compiler name and its initial flags stored in the libtool
147# configuration file don't match those in the command line, libtool
148# can't decide which configuration to use, and it gives up.  The
149# correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe
150# CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to
151# attempt to infer which configuration to use.
152# 
153# The second tag argument, `--tag disable-shared` means that libtool
154# only compiles each source once, for static objects. In actuality,
155# glibcxx_lt_pic_flag and glibcxx_compiler_shared_flag are added to
156# the libtool command that is used create the object, which is
157# suitable for shared libraries.  The `--tag disable-shared` must be
158# placed after --tag CXX lest things CXX undo the affect of
159# disable-shared.
160
161# 2) Need to explicitly set LTCXXCOMPILE so that EXTRA_CXX_FLAGS is
162# last. (That way, things like -O2 passed down from the toplevel can
163# be overridden by --enable-debug.)
164LTCXXCOMPILE = \

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