Update: you are right -- it works on XP, but I am on Windows 7.
While installing on Cygwin the packages required to compile GRASS, it 
occurred to me I had read on Cygwin website that Windows 7 would have 
been supported starting next major version 1.7 (see http://cygwin.com/). 
However, 1.7 is in beta testing and available to install, which I did. 
Things work much better, and now GRASS 6.4.0RC5 starts up fine with 
tcltk gui.

First problem I encountered next is with the dbf driver. The output of 
/db.connect -p/ seems ok:

driver:dbf
database:$GISDBASE/$LOCATION_NAME/$MAPSET/dbf/
schema:
group:

But when I do /db.test test1/ errors arise:

create table grass_test1 (i1 integer, d1 double precision, c1 varchar(20))
EXECUTE: OK
insert into grass_test1 values ( 1, 123.456, 'abcd' )
EXECUTE: OK
insert into grass_test1 values ( 2, null, 'xxx' )
EXECUTE: OK
select * from grass_test1
EXECUTE: OK

Any idea what happens and/or testing hints for better diagnosis?
Kind regards,
