http://sourceware.org/cgi-bin/pdw/ps_form.cgi, project Cygwin, approver me.

However, I just had another look into your patch and I have a problem
here.  On what system and with what type of user account did you test?

Here's what I get on Windows 2008 and W7:

$ ~/tests/access /proc/registry/HKEY_PERFORMANCE_DATA
access (/proc/registry/HKEY_PERFORMANCE_DATA, F_OK) = 0
access (/proc/registry/HKEY_PERFORMANCE_DATA, R_OK) = -1 <Permission denied>
access (/proc/registry/HKEY_PERFORMANCE_DATA, W_OK) = -1 <Read-only file system>
access (/proc/registry/HKEY_PERFORMANCE_DATA, X_OK) = -1 <Bad file descriptor>

The result is the same on W7 and 2008.  I tried with a normal user
account, as well as with an admin account, with full rights as well as
UAC-restricted.
