I will try. First is libstdc++.

1. It doesn't make sense to use c++, which adds -lstdc++, to build
libstdc++.so. The gnu ld will add libstdc++.so to the needed list
for libstdc++.so. It is very strange to the least.

2. You cannot use the same soname for libstdc++ for linux/libc5 and
linux/glibc 2. It will confuse users and may cause many problems.

	* Makefile.in ($(SHLIB)): Use $(CC) instead of (CXX) to avoid
	implicit -lstdc++.

	* configure.in (*-*-linux*gnulibc1): Add linux-gnulibc1.ml
	for frags to avoid soname conflict.

	* config/linux-gnulibc1.ml: New.
