I have Git for Windows installed on a Windows 7 machine (no, sadly I can't switch to W10 on this particular machine). This comes with a bash environment that uses MinGW-64 but only includes some binaries. I'd like to add more, such as GCC.
It seems like there should be someway of adding to the MinGW-64 binaries within the git bash instead of adding a whole other MSYS2/MinGW-64 install. However I'm not exactly clear on what is the best way to go about enabling this. I have tried installing win-builds in the bash install
usr/ directory (seemed like the place all the other binaries were). It seems to run OK but it doesn't seem to add anything AFAICT, no executables, no folders, nada... except if I try to run the install again it complains that there are already files there... though they patently aren't.
Thus my question is this: can I use win-builds or some other binary to achieve my aim and if so, how?
Note: There are several questions about this around the net and SE, but most are quite old and so no longer relevant AFAICT due to changes in MSYS2, MinGW and Git for Windows.
