The reason for this behavior is most likely caused by both Microsoft Visual Studio and MinGW being installed. The current SCons setup for V8 depends on the SCons autodetecting the toolchain, where MSVC is preferred over MinGW. You could try patching SConstruct and src/SConscript files adding tools = ['mingw'] to Environment() calls (Environment(tools = ['mingw'])). On a Windows installation with only MinGW installed V8 SCons build does not cause problems.
