Oops!  I tested it on Windows, so it works OK with the std build.

Nobody does, alas.  Mark Hammond and I have a delayed date to rework that.

Sounds par for the course.

Ya:  the great thing about all these macros is that they're usually worse
than useless (you try them, they break something).  The _sre project has

    /export:init_sre

buried in its link options.  DL_EXPORT(void) expands to void.  Not pretty,
but it's the way everything else (outside the pythoncore project) works too.
