# libstdc++ libtool notes

# 1) Need to explicitly set LTCXXCOMPILE so that AM_CXXFLAGS is

# last. (That way, things like -O2 passed down from the toplevel can

# be overridden by --enable-debug.)

# 2) In general, libtool expects an argument such as `--tag=CXX' when

# using the C++ compiler, because that will enable the settings

# detected when C++ support was being configured.  However, when no

# such flag is given in the command line, libtool attempts to figure

# it out by matching the compiler name in each configuration section

# against a prefix of the command line.  The problem is that, if the

# compiler name and its initial flags stored in the libtool

# configuration file don't match those in the command line, libtool

# can't decide which configuration to use, and it gives up.  The

# correct solution is to add `--tag CXX' to LTCXXCOMPILE and maybe

# CXXLINK, just after $(LIBTOOL), so that libtool doesn't have to

# attempt to infer which configuration to use

# 3) We'd have a problem when building the shared libstdc++ object if

# the rules automake generates would be used.  We cannot allow g++ to

# be used since this would add -lstdc++ to the link line which of

# course is problematic at this point.  So, we get the top-level

# directory to configure libstdc++-v3 to use gcc as the C++

# compilation driver.
