>Description:
I configured ss-20010521 with
--enable-debug --enable-cxx-flags='-fno-omit-frame-pointer'

As a result, the inlined functions in standard header
files like cstring are not included in the library.

This results in total failure to compile a C++ program
with errors like:

When also -fkeep-inline-functions is used in --enable-cxx-flags
then things work again.  No idea what would be a good way to fix
this though.
