[Bug 19533] reg.exe missing most options; breaks firefox and chromium builds

Chromium's build also executes the batch file
http://src.chromium.org/viewvc/chrome/trunk/deps/third_party/cygwin/setup_mo...
which contains the line
reg add "%MOUNT_KEY%" /v "cygdrive flags" /t REG_DWORD /d 34 /f 
which fails with the messages

ADD - HKCU\Software\Cygnus Solutions\Cygwin\mounts v0 cygdrive flags 0
REG_DWORD 34 1
Unhandled Type 0x4  data 34
The operation completed successfully

(Despite the failure, it claims the operation was successful.)
I'll attach a patch that gets past this problem.
