+ EMACS_TIME simplification (Bug#11875).
+ This replaces macros (which typically do not work in GDB)
+ with functions, typedefs and enums, making the code easier to debug.
+ The functional style also makes code easier to read and maintain.
+ * systime.h: Include <sys/time.h> on all hosts, not just if
+ WINDOWSNT, since 'struct timeval' is needed in general.
+ (EMACS_TIME): Now a typedef, not a macro.
+ (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
+ not macros.
+ (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
+ (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)
+ (EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE, EMACS_TIME_LT)
+ (EMACS_TIME_LE): Now functions, not macros.
+ (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
+ (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
+ which are not functions. All uses rewritten to use:
+ (make_emacs_time): New function.
+ (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
+ (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
+ not functions. All uses rewritten to use the following, respectively:
+ (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
+ (add_emacs_time, sub_emacs_time): New functions.
+ * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
+ * fileio.c (Fcopy_file):
+ * xterm.c (XTflash): Get the current time closer to when it's used.
+ * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.
+
+ * bytecode.c (targets): Suppress -Woverride-init warnings.
+
Simplify by avoiding confusing use of strncpy etc.
* doc.c (Fsnarf_documentation):
* fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
