Thanks very much for your reply Stas. Pardon my ignorance, but are you
saying I need to rebuild Perl with different options.

Unfortunately (at least for a time being) yes.

The version of
Perl I'm using is the packaged one I installed with the cygwin install
utility.  If this is the case, could you please a little more
information as to the arguments you recommend to build a version of Perl
that works fine 'standalone', as well as embedded (which I presume is
the case with mod-perl) if that is possible.

Currently mod_perl 2.0 supports the multiple Perl interpreters only if perl has been built with -Dusethreads. This may change in the future, or may be not.

For now please build with:

./Configure -des -Dusethreads [...]

or (assuming that perl automatically turns on this option, which I doubt):

./Configure -des -Uusemultiplicity [...]

I think if you build by yourself, all you need is:

./Configure -des

(-des picks all the defaults)

what's important is that when your perl has been built, it should either have:

usethreads=define useithreads=define usemultiplicity=define

or

usethreads=undef useithreads=undef usemultiplicity=undef

in the output of:

% perl -V | grep usethreads

We can take two approaches, patch all the places in the code where perl
context is set explicitly to use #ifdef MULTIPLICITY, rather than

#ifdef

USE_THREADS. Or we can refuse to build mod_perl if MULTIPLICITY is enabled without the threads. Of course the first solution is more favorable for users.

I've played a bit with various options and it seems that it's going to
be a big trouble to support MULTIPLICITY without USE_THREADS. My suggestion
for now is to either rebuild with -Uusemultiplicity or -Dusethreads (less
preferred if you don't need threads, but need speed). README.cygwin says:

=item * C<-Dusemultiplicity>

Multiplicity is required when embedding Perl in a C program and using
more than one interpreter instance. This works with the Cygwin port.

Though I can't see that this is a required option.
