1.6 --------------------------------
1.7 +Symptoms:
1.8 + Installing the C library headers and start files fails because of
1.9 + missing unwind support, with a message like:
1.10 + configure: error: forced unwind support is required
1.11 +
1.12 +Explanations:
1.13 + The issue seems to be related to building NPTL on old versions
1.14 + of glibc (and possibly eglibc as well) on some architectures
1.15 + (seen on powerpc, s390, s390x and x86_64).
1.16 +
1.17 +Fix:
1.18 + None so far. It would require some glibc hacking.
1.19 +
1.20 +Workaround:
1.21 + Try setting "Force unwind support" in the "C-library" menu.
