Why, if you are trying to build a non-thread-supporting libc, are you not
using --enable-threads=no? Re your earlier post, it's probably not enough to
simply "not select" thread support; the default may well be "enabled".

But doesn't that mean you're now trying to build it _with_ threads?

Hmm. Maybe this is the kind of thing the --disable-sanity-checks option is

Well, what version of the compiler are you using? Does it support cleanup
handling or not? Maybe you need a more recent gcc.
Can't think of a witty .sigline today....
