From the developer:
GNUARM is a pre-compiled binary distribution for the latest GNU ARM/Newlib toolchain for Cygwin, Linux and MacOS.
The toolchain consists of the GNU binutils, compiler set (GCC) and debugger (Insight for Windows and Linux, GDB only for MacOS). Newlib is used for the C library. The toolchain includes the C and C compilers. Details of the build process appear here. The Windows installer executable files are generated with Inno Setup.
