3/27    Anyone have experience with embedded Perl in C/C++ apps? I've been
        using this for a while but now I find out I can't "use POSIX" for
        example in the Perl code, and trying to follow instructions on
        the internet for how to load extensions like this doesn't seem to
        work. So, maybe someone can help describe what should be done...
        I tried putting in an xs_init function generated by ExtUtils, but
        for example when the DynaLoader tries loading POSIX it can't
        resolve symbols that come from perl.h (PL_sig_name).
