* modules/sys_time (Makefile.am): Build sys/time.h only when it's the value of $(SYS_TIME_H). [MOSTLYCLEANFILES]: Now that sys/time.h is created only when needed, remove it conditionally, too. * m4/sys_time_h.m4 (gl_HEADER_SYS_TIME_H_BODY): Set SYS_TIME_H. * m4/gettimeofday.m4 (gl_FUNC_GETTIMEOFDAY): (gl_FUNC_GETTIMEOFDAY_CLOBBER): Set SYS_TIME_H when setting GETTIMEOFDAY_REPLACEMENT to 1. 2007-01-28 Bruno Haible <bruno@clisp.org>
