Thanks Laurent. I've extracted an incremental diff for the Makefile and targtyps.c changes and applied it to my gcc-4.4.1 version. When it has finished its rebuild I'll see if this lets me eliminate the xsinfo.adb exception handling workaround. > It would be nice to have a ZCX port but so far the sjlj exceptions > based port works fine. See e.g. <http://gcc.gnu.org/ml/gcc-patches/2009-02/msg00509.html>. Apparently ZCX on ARM/EABI will require a new personality routine. /Mikael
