[lttng-dev] liburcu patch for compilers without __thread support

[Marek Vavruša]

Hello,

we're using liburcu for our DNS server. It's really clever, but we
needed to get it running under NetBSD/OpenBSD and OS X.
Since compilers on those platform don't have support for __thread
keyword, I have made a patch that detects such a compiler
and uses compatibility implementation with
pthread_getspecific()/pthread_setspecific(). I have attempted to make
it as least intrusive
as possible. TLS variables are now declared/defined with a set of
macros in urcu/tls-compat.h

The patch is against the latest release tag v0.6.7 (git format-patch),
but should work with latest git head save for configure.ac
Please let me know what you think and how could we incorporate it to upstream.

Cheers,
Marek
