New Comment:
The constants are system dependent.
If your system doesn't define them, PHP should do so.
The goal of the test is to make sure they are defined, not
their value.

Description:
------------
Running make test on 5.2.0RC4 fails with:
FAIL Math constants [ext/standard/tests/math/constants.phpt]
Reproduce code:
---------------
Add this additional debug to run-tests.php at line 1494:
$output_pgarr = explode("\n", $output);
$wanted_pgarr = explode("\n", $wanted);
foreach($wanted_pgarr as $line) {
list($pgleft, $pgright) = explode(":", $line, 2);
$pgleft = trim($pgleft); $pgright = trim($pgright);
$pgwanted[$pgleft] = "$pgright";
}
foreach($output_pgarr as $line) {
list($pgleft, $pgright) = explode(":", $line, 2);
$pgleft = trim($pgleft); $pgright = trim($pgright);
if (strcmp($pgright, $pgwanted[$pgleft]) !== 0)
printf("%-10s: Expected: %-16s Got: %-16s Diff: %s\n", $pgleft,
$pgwanted[$pgleft], $pgright, bcsub($pgwant
ed[$pgleft], $pgright,12));
}
% echo "ext/standard/tests/math/constants.phpt" > pgtest.txt
% php run-tests.php -l pgtest.txt
Expected result:
----------------
Expected test to PASS
Actual result:
--------------
Added more code to run-tests.php to report on what was going on and
got:
