This file documents the port of Mercury to Windows using
Cygwin (i.e the x86_64-pc-cygwin configuration).
The x86 (32-bit) version of Cygwin has reached its end-of-life and is no longer supported by Mercury.
Installations of Mercury on Cygwin will use the Cygwin port of the GNU C
compiler (GCC) by default. When using the Cygwin port of GCC, programs will
have a dependency on the Cygwin DLL (cygwin1.dll).
You may also use the Cygwin environment to build a Mercury installation that uses an alternative C compiler, such as Microsoft Visual C. (See README.MS-VisualC.md and README.MS-Windows.md for further details.)
