181# Libtool notes
182
183# 1) In general, libtool expects an argument such as `--tag=CXX' when
184# using the C++ compiler, because that will enable the settings
185# detected when C++ support was being configured.  However, when no
186# such flag is given in the command line, libtool attempts to figure
187# it out by matching the compiler name in each configuration section
188# against a prefix of the command line.  The problem is that, if the
189# compiler name and its initial flags stored in the libtool
190# configuration file don't match those in the command line, libtool
191# can't decide which configuration to use, and it gives up.  The
192# correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe
193# CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to
194# attempt to infer which configuration to use.
195# 
196# The second tag argument, `--tag disable-shared` means that libtool
197# only compiles each source once, for static objects. In actuality,
198# glibcxx_lt_pic_flag and glibcxx_compiler_shared_flag are added to
199# the libtool command that is used create the object, which is
200# suitable for shared libraries.  The `--tag disable-shared` must be
201# placed after --tag CXX lest things CXX undo the affect of
202# disable-shared.
203
204# 2) Need to explicitly set LTCXXCOMPILE so that EXTRA_CXX_FLAGS is
205# last. (That way, things like -O2 passed down from the toplevel can
206# be overridden by --enable-debug.)

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

220# compilation driver.
