boost and mingw64 (msys)

[3rav]

I have error with boost library:

checking whether errno is thread save... no
checking which flag to use to enable OpenMP... -fopenmp
checking for boostlib >= 1.54... yes
checking boost/pool/pool_alloc.hpp usability... yes
checking boost/pool/pool_alloc.hpp presence... yes
checking for boost/pool/pool_alloc.hpp... yes
checking whether the Boost::System library is available... yes
configure: error: Could not find a version of the library!

but if I have --with-boost=no the compilation is OK.
