Hi Kirill, thanks for looking into this. kkm> I just did the test, and got the correct results. Could it be kkm> that b31 went out with library versions of stat/fstat? I'll kkm> put a note into nt.c describing this problem. Oh, another thing: I built XEmacs 21.2-b31+ from CVS yesterday with USE_PORTABLE_DUMPER=1 See my Success build-report to xemacs-beta. I had convinced myself that this was not causing the file-exists-p problem, but maybe it is after all. Will try building wiht USE_PORTABLE_DUMPER=0 to find out for sure.
