I'd go for B) and change it, since it's easy and the p suffix is quite
common... here's a patch that does it:

version_compare does handle suffixes. (see example below) However, p1
is not a valid suffix for this function. So, solutions would be imo:
A) use the pl suffix and document this
B) make version_compare handle pl and p equally

Example script:
<?php
$version[] = "4.0.1pl2";
$version[] = "4.0.1pl1";
$version[] = "4.0.1b";
$version[] = "4.0.1a";
$version[] = "4.0.1p1";
$version[] = "4.0.1";
printf("%10s | %10s | %10s\n", "Version 1", "Version 2", "New Vers.");
print str_repeat('-',36)."\n";
for ($i = 0, $s = count($version); $i < $s; $i++ ) {
for ($j = $i; $j < $s; $j++) {
printf("%10s | %10s | ",$version[$i],$version[$j]);
$c = version_compare($version[$i], $version[$j]);
switch ($c) {
case -1:
$r = $version[$j];
break;
case 0:
$r = 'equal';
break;
case 1:
$r = $version[$i];
}
printf("%10s\n", $r);
}
}
?>

Result:
Version 1 | Version 2 | New Vers.
------------------------------------
4.0.1pl2 | 4.0.1pl2 | equal
4.0.1pl2 | 4.0.1pl1 | 4.0.1pl2
4.0.1pl2 | 4.0.1b | 4.0.1pl2
4.0.1pl2 | 4.0.1a | 4.0.1pl2
4.0.1pl2 | 4.0.1p1 | 4.0.1pl2
4.0.1pl2 | 4.0.1 | 4.0.1pl2
4.0.1pl1 | 4.0.1pl1 | equal
4.0.1pl1 | 4.0.1b | 4.0.1pl1
4.0.1pl1 | 4.0.1a | 4.0.1pl1
4.0.1pl1 | 4.0.1p1 | 4.0.1pl1
4.0.1pl1 | 4.0.1 | 4.0.1pl1
4.0.1b | 4.0.1b | equal
4.0.1b | 4.0.1a | 4.0.1b
4.0.1b | 4.0.1p1 | 4.0.1b
4.0.1b | 4.0.1 | 4.0.1
4.0.1a | 4.0.1a | equal
4.0.1a | 4.0.1p1 | 4.0.1a
4.0.1a | 4.0.1 | 4.0.1
4.0.1p1 | 4.0.1p1 | equal
4.0.1p1 | 4.0.1 | 4.0.1
4.0.1 | 4.0.1 | equal

Um, PHP version 5.0.0b1 is a PHP version with a suffix. I'd call this
a valid bug, especially because this can be fixed by using
strnatcasecmp() instead of version_compare(). Perhaps this is a bug in
version_compare(), and should be noted as such?

Yes many developers have this problem because of lack of
documentation.

Opening back as a documentation problem (even if we don't have this
category for PEAR and btw we should have more categories for PEAR).

Can anyone write a little <para> on this?

this should be then at least noted in the PEAR developer
documenation... My package is not the first one with this problem....
(and using p1 as suffix is pretty standard for software versions) so
that note is needed.
