Thanks Hans,

So ... Msys builds Windows executables
And ... I have to specify Windows-style directory names?

Notice the "mixed message" that I got .... executable in C:\Msys ....
and missing file in the style of the Msys shell.

I should have mentioned, that this works perfectly on cygwin.
I'm now trying to build the cygwin sources on Msys and cygwin to see
if I can get a working pgm.

Note also, that bison was initially installed from the binary distro ...
I didn't build it ... it just didn't work.
