Tags: experimental, patch
Hi,
the Hurd/Mach still has no TLS or __thread support. This is not that
big of a problem as there is --without-tls, but glibc-2.4 uses __thread
unconditionally at one place and Ulrich Drepper refused to support
systems without __thread support (see
http://sourceware.org/ml/libc-alpha/2005-08/msg00091.html ).
The attached patch fixes building on system without __thread support
(i.e. hurd-i386), is it OK to apply to the 2.4 branch?
cheers,
Michael
