chdir-long, cycle-check, savewd: better 'inline' * lib/chdir-long.c (cdb_init, cdb_fchdir, cdb_free) (find_non_slash): * lib/cycle-check.c (is_zero_or_power_of_two): * lib/savewd.c (savewd_delegating): Change 'static inline' to 'inline'. * lib/savewd.c, lib/savewd.h (SAVEWD_INLINE): New macro. Replace all remaining uses of 'static inline' with it. * lib/savewd.h: Use _GL_INLINE_HEADER_BEGIN, _GL_INLINE_HEADER_END. * m4/chdir-long.m4 (gl_PREREQ_CHDIR_LONG): * m4/cycle-check.m4 (gl_CYCLE_CHECK): * m4/savewd.m4 (gl_SAVEWD): Do not require AC_C_INLINE. * modules/savewd (Depends-on): Add extern-inline.
