[lmi] Displaying messages during wx startup

[Greg Chicares]

Consider the patch below, which attempts to display a warning message
on the first line of the main function. Is there some way to make the
wxLogWarning message get displayed, even before wx has been initialized?
I suspect the answer is "no", which is okay by me as long as I can find
a way to test whether it's not going to work--is there a way?

This reduced testcase is silly in itself, of course. What I'm really
looking for is a way to make this function robust:

// from 'alert_wx.cpp':
void warning_alert(std::string const& s)
{
    wxLogWarning(s.c_str());
    wxLog::FlushActive();
}

even when it's called during initialization of a global object.
I'm hoping there's a Condition() such that this will work:

+  if(Condition())
+    {
     wxLogWarning(s.c_str());
     wxLog::FlushActive();
+    }
+  else {safely_show_message(s);}
