>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:
~/c++/libcw/src/libcwd>g++-3.0 -v test.cc

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.

Please close this PR again... it turns out to be solved AFTER the
latest snapshot (on the day it was released).
Thanks,
