It's not necessarily obvious.

Actually, it's otherwise.

The life-insurance calculations are factored into a library.
LMI_USE_SO_ATTRIBUTES governs how to build that library.

'wx_new.?pp' is an attempted workaround for what seemed to me
to be a conflict between wx and mpatrol. Vadim has suggested
that the real issue is neither of those libraries, but rather
MinGW's use of a non-shared libstdc++. Anyway, 'wx_new.?pp'
must always be built as a shared library in order for this
workaround to have its intended effect.

Probably it's harmless to build it any other way; it just
won't have that intended effect.

And the whole scheme doesn't work well at all since gcc-3.2.3,
so I guess it doesn't matter much to the work you're doing.
But maybe it'll become useful again when gcc-4.x becomes
stable for msw.

Yes, let's postpone this. I'll add some comment to this file
when I merge it with HEAD. I don't think it's worth spending
more time on until we have a stable msw port of gcc-4.x .
