gnulib: lib/sys_select.in.h annotate

annotate lib/sys_select.in.h @ 15328:c7ae1577bd26

sys_select: don't depend on sys_socket This is so that Emacs doesn't have to drag in m4/sockpfaf.m4 etc; see <http://lists.gnu.org/archive/html/bug-gnulib/2011-06/msg00358.html>. This fix works on GNU and GNU-like platforms, but has not been tested on native Windows. * lib/sys_select.in.h: Include <sys/socket.h> only if native Windows. * m4/sys_select_h.m4 (gl_HEADER_SYS_SELECT): Do not require gl_HEADER_SYS_SOCKET. * modules/sys_select (Files): Add m4/sys_socket_h.m4, for gl_PREREQ_SYS_H_WINSOCK2.
