it is not only in the thread library, the boost/interprocess library has a similar error (invalid initialization of reference type)

this code builds fine with msvc2010

with gcc 4.6 beta i get the same error.

without the -std=c++0x option it compiles ok

with boost_1_40_0 and boost_1_39_0 i also get the same error.

Trunk compiles with gcc 4.5 in -std=c++0x mode.

i cannot confirm that.

also with trunk, revision 63919 i get the above error with gcc 4.5

Clarification: Boost.Thread on trunk (revision 63919) compiles with gcc 4.5 in -std=c++0x mode (tested on Ubuntu 9.10/x86_64 with gcc-4.5 (Ubuntu 4.5-20100227-1gezakovacs~karmic1) 4.5.0 20100227 (experimental) [trunk revision 157109])
