+ (poll): Use modern idiom.
+ * modules/poll-h: New file.
+ * modules/poll (Files): Remove lib/poll.in.h.
+ (Depends-on): Add poll-h.

+ (Makefile.am): Move code for generation of poll.h to modules/poll-h.
+ * m4/poll_h.m4: New file.
+ * m4/poll.m4 (gl_FUNC_POLL): Require gl_POLL_H. Don't check for poll.h
