In summary, when a glibc version 2.3.x to 2.5 is used with a gcc version
4.3 or newer, the use of __inline in <wchar.h> leads to multiple
misbehaviours:
- miscompilation, as observed by Karl,
- link errors, as observed here:

Yes, I object. It's not only about 'btowc'. The entire <wchar.h> is
broken in this situation. The protection needs to go into m4/wchar.m4.
