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)
--
