Right, build continues but crashes later on with Qt4 errors. I'll start a
new thread for that.

My changes to get the MinGW build until this new error (BTW using Tatsuro's
dependencies and build stuff) are simple:

1. in <SRCDIR>:
libinterp/interpfcn/file-io.cc
libinterp/interpfcn/oct-hist.cc
libinterp/interpfcn/sysdep.cc
liboctave/oct-env.cc
=>   repeat the
#include <unistd.h>
  line so that it appears twice (seems and old MinGW/gnulib issue)

2. in <BUILDDIR>/libinterp/parse-tree/lex.cc (generated),
a. add:
  #include <io.h>
b. comment out L.1300: #define isatty GNULIB_NAMESPACE::isatty"

The former used to be needed in file-io.cc as well, but apparently no more.
