- 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".
