Thanks Michael.

I added -DUNICODE to CPPFLAGS (in configure options), 
(export CPPFLAGS='-DUNICODE -I/x/Programs/gplibs/include
-I/x/Programs/OctaveLibs/include -I/x/programs/GnuWin32/include' before
running configure)

but now I get:

:
libtool: compile:  g++ -shared-libgcc -DHAVE_CONFIG_H -I.
-I../../octave/liboctave -I.. -I
../libgnu -I../../octave/libgnu -I../../octave/libcruft/misc -DUNICODE

"const WCHAR" in file-ops.cc tells me that -DUNICODE might have been picked
up the wrong place. Obviously I'm doing something wrong.

Would you have other suggestions?

Philip
