[PATCH 1/6] Cygwin: Suppress array-bounds warning from NtCurrentTeb()

[Jon Turney]

This disables a warning seen with gcc 12 caused by intrinsics used by
the inline implementation of NtCurrentTeb() inside w32api headers.

> In function ‘long long unsigned int __readgsqword(unsigned int)’,
>     inlined from ‘_TEB* NtCurrentTeb()’ at /usr/include/w32api/winnt.h:10020:86,
> [...]
> /usr/include/w32api/psdk_inc/intrin-impl.h:838:1: error: array subscript 0 is outside array bounds of ‘long long unsigned int [0]’ [-Werror=array-bounds]
