However, that way of doing things require more foresight you can
imagine.  Imagine an X11 library compiled as plain C source with
-fno-exceptions. That library cannot be used reliebly by a C++
programs because if it provides a callback (with C linkage) that might
throw directly of indirectly (most frequent), GCC will not propagate
that exception properly to the program. It will just abort.  That is
an unfortunate situation.
