This is a strange problem: certain files in the Windows/System32
directory are not visible from Cygwin:
Studio(27): ls /cygdrive/c/Windows/System32/nbtstat.exe
ls: cannot access /cygdrive/c/Windows/System32/nbtstat.exe: No
such file or directory
But other ones are:
Studio(28): ls /cygdrive/c/Windows/System32/PING.EXE
/cygdrive/c/Windows/System32/PING.EXE
The system in question is Windows 7 64-bit (service pack 1), running
Cygwin 1.7.9-1. I've tried it with and without user access control
enabled, but it doesn't make a difference. CYGWIN is set to
"nodosfilewarning tty".
The problematic file (nbtstat.exe) most definitely exists and can be
run from a DOS prompt window.
Any ideas? Thanks!

Yeah, I thought so. Ever heard about file system redirection? If not,
see http://msdn.microsoft.com/en-us/library/aa384187%28VS.85%29.aspx
Hint: Try `ls /cygdrive/c/Windows/Sysnative/nbtstat.exe'
This has nothing to do with Cygwin, except that Cygwin is a 32 bit
application.

Windows is lying to you: The file is *not* there.
Windows Vista and Win7 in the 64 bit variants have the file system
redirector
(http://msdn.microsoft.com/en-us/library/aa384187%28VS.85%29.aspx,
http://msdn.microsoft.com/en-us/library/aa384249%28VS.85%29.aspx) which
makes all of this a mess.
Cygwin is a 32 bit application; this, it does NOT see
%WINDIR%\System32, but %WINDIR%\SysWOW64. I am sure nbtstat.exe does not
exist there, right?
HTH,
Spiro.
