Little extra comment: FriCAS build system normally assumes that
if file "f.lisp" exists in current directory than concatenating
output of 'pwd' with "/f.lisp" produces valid namestring usable
by Lisp.  I wrote normally, because MinGW with MySys is an
exception: 'pwd' produces Unix-style filenames, but MinGW
binaries use Windows pathnames.  For Cygwin I expect Cygwin
binaries (that is ecl) to understand output of Cygwin 'pwd'.

Martin, could you verify that that 'pwd' in top of FriCAS
source directory (where 'config.lisp' lives) really gives
'/cygdrive/d/fricas')?
