Subject: Win32: fixed C4319 warning with MSVC 2022 x86.
X-Git-Tag: release-1.29.5~13
X-Git-Url: http://www.kaiwu.me/postgresql/commit/static/gitweb.js?a=commitdiff_plain;h=6a67f71a4a78edb662c190af93ac6d3d680e107a;p=nginx.git

Win32: fixed C4319 warning with MSVC 2022 x86.

The warning started to appear in Visual Studio 2022 version 17.14.21,
which corresponds to the C/C++ compiler version 19.44.35221.

The appropriate fix is to avoid mixing uint64_t and ngx_uint_t in an
expression with bitwise operations.  We can do that here because both
the original shm->size value and the result of the expression are 32-bit
platform words.
