Potential memory access issue in x86 Windows Vista

[fafalone]

The RTL_USER_PROCESS_PARAMETERS structure has it's last member as EnvironmentSize As LongLong, this is incorrect as it should be LongPtr (ULONG_PTR). This is less of an issue on Win7+ because 7 contains an additional LongPtr member at that location, so the only issue is the value of the last parameter rather than overrunning the structure.

If this is an issue for you, change EnvironmentSize to LongPtr, until the next version is published.

Some member names are also incorrect but indicate the same thing (e.g. StdInputHandle instead of StandardInput).
