NO. automatic export do not explain the following test results: gcc-4.8, mingw-w64 trunk, binutils 2.23.2, 32 bit windows target: extra export InterlockedCompareExchange@12 gcc-4.8, mingw-w64 trunk, binutils 2.23.2, 64 bit windows target: OK gcc-4.7, mingw-w64 v2, binutils 2.23.2, 32 bit windows target: OK gcc-4.7, mingw-w64 v2, binutils 2.23.2, 64 bit windows target: OK I can not see any reason that binutils is the criminal, gcc 4.8 or mingw-w64 trunk looks more like the criminal.
