- * strftime.c
- *
- * Public-domain implementation of ANSI C library routine.
- *
- * It's written in old-style C for maximal portability.
- * However, since I'm used to prototypes, I've included them too.
- *
- * If you want stuff in the System V ascftime routine, add the SYSV_EXT define.
- * For extensions from SunOS, add SUNOS_EXT.
- * For stuff needed to implement the P1003.2 date command, add POSIX2_DATE.
- * For VMS dates, add VMS_EXT.
- * For a an RFC822 time format, add MAILHEADER_EXT.
- * For ISO week years, add ISO_DATE_EXT.
- * For complete POSIX semantics, add POSIX_SEMANTICS.
- *
- * The code for %c, %x, and %X now follows the 1003.2 specification for
- * the POSIX locale.
- * This version ignores LOCALE information.
- * It also doesn't worry about multi-byte characters.
- * So there.
- *
- * This file is also shipped with GAWK (GNU Awk), gawk specific bits of
- * code are included if GAWK is defined.
- *

-Hi Arnold,
-in a process of fixing of strftime() in libraries on Atari ST I grabbed
-some pieces of code from your own strftime. When doing that it came
-to mind that your weeknumber() function compiles a little bit nicer
-in the following form:
-/*
- * firstweekday is 0 if starting in Sunday, non-zero if in Monday
- */
-{
- return (timeptr->tm_yday - timeptr->tm_wday +
- (firstweekday ? (timeptr->tm_wday ? 8 : 1) : 7)) / 7;
-}
-How nicer it depends on a compiler, of course, but always a tiny bit.
-
- Cheers,
- Michal
