Hi Stas,
Although anything's possible, of course, I don't see at the
moment where this happened due to recent win32 changes. The
changes concerning decoupling APR from mod_perl specific to
Win32 were all wrapped around if(WIN32) {}, except for
building xs/APR/aprext/, which should do nothing on
non-Win32, as the dynamic and static targets were skipped.
Before this sequence of changes there were some Win32 ones
in the tests, but these probably are irrelevant to this
problem.
Unfortunately, I don't have a perl-5.6 available (except
for a Win32 one, but that can't build mp2). Do you know if
it was working before I committed your large patch for
decoupling APR from mod_perl.so (before any of the Win32
stuff was put in)?
I looked at my ExtUtils::Embed. One, version 1.2505, has
$root = $MM->catdir(@ns);
where
my $MM = bless {} => 'MY';
from a few lines earlier. Perhaps the stray MY object
reference is related to this "MY". Can you see what
happens if you upgrade ExtUtils::Embed - version
1.25061 has the corresponding line
$root = File::Spec->catdir(@ns);
