* lib/count-leading-zeros.c: New file.
* lib/count-leading-zeros.h (COUNT_LEADING_ZEROS_INLINE):
New macro. Replace all uses of 'static inline' with it.
Use _GL_INLINE_HEADER_BEGIN, _GL_INLINE_HEADER_END.
* m4/count-leading-zeros.m4 (gl_COUNT_LEADING_ZEROS):
Do not require AC_C_INLINE.
* modules/count-leading-zeros (Files, lib_SOURCES):
Add lib/count-leading-zeros.c.
(Depends-on): Add extern-inline.
