I wonder why this hasn't been discovered before. All my currently
installed (win32) versions (4.3.[2346], 5.0.0RC1) suffer from this
problem.

Hmm, I'm confused.
Windows(2k, XP 98):
C:\>php -r "var_dump('0d1' == '0d2');" (1)
bool(true)
C:\>php -r "var_dump('00d1' == '00d2');" (2)
bool(false)
C:\>php -r "var_dump('0a1' == '0a2');" (3)
bool(false)
Unix like OS:
% php -r "var_dump('0d1' == '0d2');" (4)
bool(false)
% php -r "var_dump('0a1' == '0a2');" (5)
bool(false)
Only (1) does not bring a result to expect.

A snapshot is also the same behavior.

Description:
------------
The results of comparison differ by Windows and unix.
Windows:
c:\> php -r "var_dump(('0d1' == '0d2'));"
bool(true)
Unix like OS:
% php -r "var_dump(('0d1' == '0d2'));"
bool(false)
I expect the same behavior for both.
Reproduce code:
---------------
c:\> php -r "var_dump(('0d1' == '0d2'));"
Expected result:
----------------
bool(false)
Actual result:
--------------
bool(true)
