Good catch. I've commented code and found the error is in the function rule check-message-compiler ( properties * ) I've changed the line 117: if <target-os>windows in $(properties) to if <target-os>windows in $(properties) && !<toolset>gcc in $(properties) and the error goes away. It seems that the line 121: local has_mc = \ [ configure.builds (...) : $(properties) : message-compiler ] ; is where the problem lies. The Boost.log documentation states that "at some point the library will require a Message Compiler tool (mc.exe), which is not available in MinGW, Cygwin and some versions of MSVC Express Edition". The check seems to hurt Boost.Build when using a MINGW environment. I don't know if my change makes any sense as windows supports many compilers (clang, intel, borland, ) so maybe the "if" condition should be more complex. I've applied the change locally and regression tests are up again. Best, Ion
