From 6612118e970c54f96b69b56eb15665b3b6fb3350 Mon Sep 17 00:00:00 2001
From: Olaf Barthel <obarthel@gmx.net>
Date: Fri, 26 Aug 2005 12:39:33 +0000
Subject: [PATCH] - log(+/-0), logb(+/-0), log10(+/-0) now return -infinity.

- getcwd() now considers a buffer size of 0 an error, and it sets
  the errno code to ERANGE if the buffer is too small.

- With Unix path semantics enabled, rename() now fails if either
  the old or the new name are empty strings. Same thing for
  opendir(), utime(), unlink(), chown(), link(), readlink(),
  realpath(), chdir(), access(), stat(), rmdir(), lstat(),
  chmod(), statfs() and open()/fopen().

- Fixed several issues with the formatted output of strftime()
  for the "C" locale: "%p" could return " PM", "%c" is now
  equivalent to "%a %b %e %T %Y", "%x" is equivalent to "%m/%d/%y"
  and "%X" is now equivalent to "%T".
