In msys2/msys2-runtime@ae5462a53b (CI: fix the build with gcc 13,
2023-11-10), we worked around build errors that look like this:
In member function ‘virtual ssize_t fhandler_console::write(const void*, size_t)’:
cc1plus: note: source object is likely at address zero
In function ‘long long unsigned int __readgsqword(unsigned int)’,
inlined from ‘_TEB* NtCurrentTeb()’ at /usr/include/w32api/winnt.h:10013:86,
inlined from ‘tmp_pathbuf::~tmp_pathbuf()’ at winsup/cygwin/local_includes/tls_pbuf.h:21:5,
inlined from ‘virtual ssize_t fhandler_console::write(const void*, size_t)’ at winsup/cygwin/fhandler/console.cc:4047:1:
/usr/include/w32api/psdk_inc/intrin-impl.h:838:1: warning: array subscript 0 is outside array bounds of ‘long long unsig
ned int [0]’ [-Warray-bounds=]
838 | __buildreadseg(__readgsqword, unsigned __int64, "gs", "q")
| ^~~~~~~~~~~~~~
This happens since the recent upgrade in MSYS2 from GCC 11.3.0-4 ->
13.2.0-2.
The work-around was to add the big hammer `-Wno-error`, which was later
toned down to `-Wno-error=array-bounds`, among other more surgical
options, in msys2/msys2-runtime@76fd7eae5a (fixup! CI: fix the build
with gcc 13, 2023-12-22).
Helpfully, a work-around for the actual compile error was proposed in
https://sourceforge.net/p/mingw-w64/mailman/message/37674508/ on
the mingw-w64-public mailing list. Let's use that for now.
