Hello,
Trying to find the problems with gprbuild, see bug #673015, the
traceback function used for GNU/Hurd caused a segfault for gprconfig.
Digging further revealed that the GNU/Hurd stack frame does not seem to
be static enough to define USE_GENERIC_UNWINDER in gcc/ada/tracebak.c.
However, USE_GCC_UNWINDER works (and the dummy version of course)! The
patch is inlined below.
