GCC from ports uses DWARF2 exception unwinding while GCC in src tree
uses sjlj exceptions. The exception handling code generated by these two

Pretty much each and every C++ binary and shared library will have to be
recompiled. Massive binary compatibility breakage is not an option for
-STABLE, one can hope.
