Hi Mikko,

I saw this post, it was useful to get me started in the right direction, but
it did not work because it wanted to use pthreads instead of mthreads.
using the -d+2 flag to see what was happening ...

    "/home/paul/mingw/bin/mingw32-g++"  -ftemplate-depth-128 -O3
-finline-functions -Wno-inline -Wall -pthread  -DBOOST_ALL_NO_LIB=1
-DNDEBUG  -I"." -c -o
"bin.v2/libs/test/build/gcc-mingw-3.4.5/release/link-static/threading-multi/unit_test_log.o"
"libs/test/src/unit_test_log.cpp"

mingw32-g++: unrecognized option `-pthread'

did you compile it on windows-mingw or linux-mingw ?

cheers
Paul
