Applying these all together and running the pc-linux-gnu binary
with '--ash_nazg', I try:
  Test | Test alerts from shared library | Test catastrophe report
Result: "Test catastrophe report." prints on the console, and no
message box appears. Is that the intention?

IOW, in this function:

void report_catastrophe(char const* message)
#if defined LMI_MSW
        ,"Catastrophic error"
#endif // defined LMI_MSW

can we write an "#else if defined LMI_POSIX && defined __WXGTK__"
clause that pops up a GUI message box even if wx or GTK has
not yet been initialized?
