Hi All,
 
I have a warning when compiling some code using a condition variable (unused variable in boost/thread/pthread/condition_variable.hpp on line 53).
It seems there is a patch for it but it has not been applied to 1.47.0 despite being quite old:
 
https://svn.boost.org/trac/boost/attachment/ticket/4818/boost-thread-pthread-condition_variable.hpp.diff
 
I have tested the patch it works for me (Ubuntu / GCC 4.5 / -Wall).
 
 
Hoping this helps,
 
Best regards,
 
 
Julien
