|Environment Variable: MAKEMSI_MINGW|
This environment variable needs to be set if you require the use of the "DllCa-C" command (unless you have added its "bin" directory to the "PATH" environment variable) as commands such as "gcc.exe" are executed without their PATH being specified.
It points to the root directory where you installed the MinGw tools. This directory should contain the "bin" directory.
If you haven't set up this environment variable then the MAKEMSI will attempt to locate it. If you install "MinGw" in a directory called "C:\MinGw" or "C:\Program Files\MinGw" then you don't need to configure this environment variable yourself.
