The mingw-w64 project is a complete runtime environment for gcc to support (I never use MSVC) I like no install, direct to use, compact, working, things. Attempted to install MinGW for the first time, via the installer (today 27 feb around 22 GMT), install dir C:\MinGW. Got as far as un-gz'ing / un-tar'ing the g++ . Cygwin software to install, including gcc, make, and gdb. The variant MinGW- w64, also called MinGW64, can also produce bit programs. GCC then functions as a cross-compiler, running on Cygwin but produc‐ing Windows programs.
