What you will be building will be a cross compiler, using either the mingw runtime or the cygwin runtime. The resulting .exe will be precisely identical to the .exe you would get from running a native gcc of the same flavor under Windows, so if your goal is to fix some kind of problem then doing this will have no affect whatsoever. Cross compilers are about developer convenience of not having to reboot to another operating system or log on to another system, and the whole point is that the binaries generated for a given target are precisely identical regardless of the host operating system. There is no such thing as "just produce an .exe" in a vacuum, there is always some form of an underlying system C runtime library that the compiler must use (i.e. have headers and libraries installed), and in the case of gcc your main choices are mingw or cygwin.
