I tried pretty much the same thing with the attached files (test.c generates a very big file, stat.c checks its size, cygcheck.out is available at http://blytkerchan.chez.tiscali.fr/cygcheck.out (md5 sum: 56aa8e6d575d27bf8a2b740a25e13dd0) because it's rather large and not very interesting. Worked like a charm !
