Dunno where you got that make.bat, this is the original make.bat
content:

@ECHO OFF
SETLOCAL
SET DEVKIT=%~dp0..\devkit
SET PATH=%DEVKIT%\gcc\3.4.5\bin;%DEVKIT%\msys\1.0.11\bin
bash.exe --login -i -c "make %*"

mkmf will generate MSYS paths, used by msys-make, as you can see from
the wrapper make.bat

I recommend you clean your current DevKit installation and verify the
proper batch files are being used.

A second recommendation, unless you're really using C++ (which I doubt
since Ruby extension API is C), please name the files .c instead
