At first I did not have Msys at all, and did not realise that it was needed.  Needless to say, "./Build" failed horribly at a CMD prompt.  I then installed "msys-base" from the MinGW GUI installer window (and later, mingw32-gcc-g++ and mingw-developer-toolkit, when I found that one or both were needed), created a shortcut called "Msys" in D:\MinGW\msys\1.0 with "Start in" set to D:\MinGW\msys\1.0\bin as recommended in Msys.bat :

but still encountered problems (such as "No C compiler in path").

Finally I added D:\MinGW\bin, D:\Mingw\Msys\1.0 and D:\Mingw\Msys\1.0\bin to the front of the system-wide path, launched a normal CMD window (in order to pick up the modified path) and typed "Msys". 

That launched the Msys window to which I referred in my earlier message.

Whether this will allow me to compile and link XeTeX, I still do not know; it has been running now for about two hours, and still shews no signs of completion.  The incantation to launch this was taken and modified from Karl's "Build one package" instructions :

> cd Work
> # Do the configure:
> ../configure --disable-all-pkgs --enable-xetex -C CFLAGS=-g CXXFLAGS=-g
> # Do the make:

but I am not yet in a position to try :

Of course, this is a 32-bit build; only once that works will I try to see if I can work out how to convert :

> ./Build --build=x86_64-w64-mingw32 --host=x86_64-w64-mingw32 
into the corresponding incantations for "Configure" and/or "Make".
