I'm afraid putting that code into the library might be worse, for
these reasons:

  1) Library modules are linked after all the object files.  Since
     functions with the `constructor' attribute are processed in the
     order they are seen by the linker, this means that users cannot
     use exception in their own functions which they declare
     "__attribute__((constructor))".

  2) We are introducing subtle but significant coupling between djdev
     and GCC, which as I understand DJ doesn't want.

  3) If somebody wants to link a C++ program with their own libc, they
     will need to remember to roll their own equivalent of crtf, or
     else have subtle bugs in exception handling.
