Bug: Error using GetProcessWorkingSetSize

[Mann Ern Kang]

Hi,

The out parameters for the Win32 API call GetProcessWorkingSetSize are
defined incorrectly in
random/rndw32.c<http://git.gnupg.org/cgi-bin/gitweb.cgi?p=libgcrypt.git;a=blob_plain;f=random/rndw32.c;hb=HEAD>.
The parameters minimumWorkingSetSize and maximumWorkingSetSize should be
declared to be of type SIZE_T, not DWORD. See
http://msdn.microsoft.com/en-us/library/windows/desktop/ms683226%28v=vs.85%29.aspx.
On Windows x64, SIZE_T is 64 bits wide, so the call can end up
erroneously overwriting part of the stack, causing a crash.

Cheers,
Mann Ern
