This already came up a few times (PowerDNS recursor, MariaDB on some arch), I don't think it was a bikeshed, the impression I got was that it probably wouldn't go in even if someone sent a diff. Most other programs wanting ucontext.h functions have some fallback code. For unwind, there may possibly be something that could be borrowed from boehm-gc...
