| Subject: | Build fails on Mac OS X Snow Leopard - symbols from perl clash with iostream |
When building the module, an error occurs because perl.h defines the do_open and
do_close macros (without the Perl_ or PL_ prefix) and these clash with the same-named ones
from iostream. A quick workaround would be to call
#undef do_open
#undef do_close
just after including perl.h.
