Summary:Mingw gcc 3.4.2 problematic
Project:pgchem::tigress

When compiling checkmol/matchmol/Barsoi on Win32 with the current MinGW gcc 3.4.2, all optimizations lead to slower code. Using a different gcc like 3.3.1 generates executables 3 times faster than without optimization. If you have speed problems, please check your compiler and then recompile Barsoi (libbarsoi.dll) with -O2 or download the separate libbarsoi.dll that was released for the Win32 runtime.
