56f8195fe5 - Nuke empty_string. It is a reminanent from the time where RETURN_FALSE()
used to return "" and not bool(false). It's not worth keeping it because
  STR_FREE() and zval_dtor() always have to check for it and it slows down
  the general case. In addition, it seems that empty_string has been abused
  quite a lot, and was used not only for setting zval's but generally in
  PHP code instead of "", which wasn't the intention. Last but not least,
  nuking empty_string should improve stability as I doubt every place
  correctly checked if they are not mistakenly erealloc()'ing it or
  calling efree() on it.
  NOTE: Some code is probably broken. Each extension maintainer should
  check and see that my changes are OK. Also, I haven't had time to touch
  PECL yet. Will try and do it tomorrow.

e6281ab38b Don't use fp arithmetic for int results
# FP arithmetic is not accurate enough on 64-bit archs
# This patch relies on ZEND_SIGNED_MULTIPLY_LONG(),
# so that should be fixed as well.

d8fbd1acef Fix Bug #21523 - number_format could cause a memory allocation for a
negative memory size in situations where the sprintf implementation of the
host system generated less decimal places than were requested.

Resolved this issue by making number_format examine the string returned
by spprintf and have it pad to the correct number of decimal places.

Added a test-case based on the bug report; the length of decimal places
required to trigger this bug is sprintf implementation dependent; as the
implementation is now using spprintf (provided by PHP), that number is
78 digits (NDIG - 2).

# I played with the idea of enhancing sprintf to do the equivalent, but
# it was too much effort considering that the precision of floats/doubles
# is not good enough to warrant it.

# This fix could do with some QA from someone else to make sure there are
# no memory bounds problems and then MFH it to PHP_4_3

stdlib.h, not math.h.

f174bbc711 Use the zend_* versions of finite(), isinf(), and isnan(), as defined
in php_config.h.  Redefine the zend_* versions in the case of Win32.

This fixes the build on systems that don't provide a native version of,
say, isinf() (e.g. Solaris).
