I used 4.9.2, but you can use any version you like. Download: Config – GCC i386 – Tools i386. Alternatively, you can install a new instance of Cygwin in a different folder. The --enable-languages=c,c++ option means that only the C and C++ compilers will be built. The new compiler is already configured to locate its include files in /usr/local/include/c++/4.9.2 and its static libraries in /usr/local/lib. First, download and run either the 32- or 64-bit version of the Cygwin installer, depending on your... 2. After you install GCC >= 4.3, some things like exception handling or shared code may not work (read more here), so install at your own risk. If you prefer to install the new GCC to a different directory, add the option --prefix=/path/to/directory to the above configure command.

Cygwin (/ ˈ s ɪ ɡ w ɪ n / SIG-win) is a POSIX-compatible programming and runtime environment that runs natively on Microsoft Windows.Under Cygwin, source code designed for Unix-like operating systems may be compiled and run natively with minimal modification. Also, when specifying higher numbers with -j, there are often strange error messages at the end of the build process involving “jobserver tokens”, but they’re harmless. I suggest moving the installer to the same folder where you installed Cygwin itself; typically C:\cygwin or C:\cygwin64. Generally it is best to keep n <= the number of real or virtual cores you have (in other words, if you have a quad core and try running -j 20 you may not be doing yourself any favors over -j 8 or possibly even -j 4, and might have other problems such as excessive swap usage that negate any possible speed improvement).
