I don't believe linking against libc_nonshared.a is correct here; instead, 
the functions should be inlined.  Why isn't Sandra's patch 
<http://www.eglibc.org/archives/patches/msg00407.html> (in current EGLIBC 
versions) working for you here?  Is __USE_EXTERN_INLINES_IN_LIBC not being 
defined, or is the compiler not inlining some of the extern inline 
functions (which sounds like a compiler bug for these particular 
functions)?
