* mode is in effect. The purpose of this function is to check if FF runs on
* Win7 OS with application compatibility mode being set to 95/98/ME.
* Those compatibility mode options (95/98/ME) can only display and
* be selected for 32-bit application.
* If the compatibility mode is in effect, the GetVersionEx function will
* report the OS as it identifies itself, which may not be the OS that is
* installed.
* Note : 1) We only target for Win7 build number greater than 7600.
* 2) GetVersionEx may be altered or unavailable for release after
* Win8.1. Set pragma to avoid build warning as error.
