Building MSYS directions were placed in the wiki.  I don't know if the 
changes that Cesar has made has made it to the instructions.

MSYS is a fork of an old Cygwin version tooled to provide MinGW a simple 
means to be able to ./configure && make and target the MinGW build 
platform.  The uname output gives value of the MSYSTEM environment 
variable as the build platform so I can easily use MSYS for MINGW32, 
MSYS, MINGW64 or something of my own design just by changing the value 
of MSYSTEM.

Cygwin has a goal to provide as close as possible POSIX emulation system 
to Windows so that you don't have to code to Windows.  You can bring 
your POSIX program and build it with Cygwin using Cygwin's special 
runtime to have it run on Windows.  Its license is such that you must 
purchase an agreement from Redhat if you want to be able to use it in a 
proprietary package.  At the time of the MSYS fork Cygwin was slower 
than MSYS and didn't cooperate well with Windows "native" applications 
where "native" is a reference to the MSVCRT.DLL runtime.

The MSYS fork has a simple goal to provide a tool to allow ./configure 
to be used for the "native" GCC processes giving the build platform of 
MINGW32.  It has allowed applications to focus on a "normal" build 
process for Windows applications where "normal" is a term for just the 
way the developer is used to building packages in POSIX.  The fact that 
MSYS is useful to accomplish more is just extra whipped topping on the pie.
