As far as I understand the rationale and the actual implementation of
your patch I like it and consider it a big improvement compared to the
current situation.
If/when the patch will be applied, you should also change
libstdc++/configure.ac, moving GCC_CHECK_UNWIND_GETIPINFO ouside the
block if $GLIBCXX_IS_NATIVE, before it, thus run unconditionally. This
additional change is pre-approved.
Thanks again,
Paolo.
