# A note on compatibility and static libraries.
# 
# static lib == linked against only this version, should not need compat
# shared lib == linked against potentially all compat versions
#
# Thus, the shared libs have more compat symbols, which can be found
# segregated in the sources with -D_GLIBCXX_SHARED.
#
# In the sub-directories of libsupc++, src/c++98, src/c++11, only
# -prefer-pic objects are generated for the convenience libraries.
# 
# In the main src directory, make shared and static objects just for
# the compat libraries. Shared objects are compiled with -prefer-pic
# -D_GLIBCXX_SHARED and in the .libs sub-directory, static objects are
# compiled with -prefer-pic (ie, -fPIC but not -D_GLIBCXX_SHARED) and
# the main src directory.
#
# Why are objects destined for libstdc++.a compiled with -fPIC? First,
# because -fPIC is not harmful to use for objects destined for static
# libraries. In addition, using -fPIC will allow the use of static
# libstdc++.a in the creation of other C++ shared libraries.

# AM_CXXFLAGS needs to be in each sub-directory so that it can be
# modified in a per-library or per-sub-library way.  Need to manually
# set this option because CONFIG_CXXFLAGS has to be after
# OPTIMIZE_CXXFLAGS on the compile line so that -O2 can be overridden
# as the occasion calls for it.

# Libtool notes

# 1) 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.
# 
# The second tag argument, `--tag disable-shared` means that libtool
# only compiles each source once, for static objects. In actuality,
# glibcxx_lt_pic_flag and glibcxx_compiler_shared_flag are added to
# the libtool command that is used create the object, which is
# suitable for shared libraries.  The `--tag disable-shared` must be
# placed after --tag CXX lest things CXX undo the affect of
# disable-shared.

# 2) Need to explicitly set LTCXXCOMPILE so that EXTRA_CXX_FLAGS is
# last. (That way, things like -O2 passed down from the toplevel can
# be overridden by --enable-debug and --enable-cxx-flags.)

# 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
