labelled "Use sjlj for exceptions".
+ Installing the C library headers and start files fails because of
+ missing unwind support, with a message like:
+ configure: error: forced unwind support is required
+ The issue seems to be related to building NPTL on old versions
+ of glibc (and possibly eglibc as well) on some architectures
+ (seen on powerpc, s390, s390x and x86_64).
+ None so far. It would require some glibc hacking.
+ Try setting "Force unwind support" in the "C-library" menu.
