The message was generated from kpathsea/readable.c .
Unix version uses access() to determine if a file is readable. I use GetFileAttributes(),
mainly because of a misbehaviour with win95, access() and stat() (failed to 
recognize directories with trailing '/').

If you can reproduce the situation, I can provide you with some kpathsea.dll to 
test. Or I could try to reproduce the problem by running tex.exe remotely through
modem ->  PPP -> samba -> my NT workstation. Maybe it will resurface.
