Subject: pgsql: Fix MinGW %d vs %lu warnings in back branches.
Date: Thu, 28 Nov 2024 22:10:59 +0000
Message-ID: <E1tGmiw-0003rr-Hi@gemulon.postgresql.org> (raw)
Fix MinGW %d vs %lu warnings in back branches.
Commit 352f6f2d used %d instead of %lu to format DWORD (unsigned long)
with psprintf(). The _WIN32_WINNT value recently changed for MinGW in
REL_15_STABLE (commit d700e8d7), so the code was suddenly being
compiled, with warnings from gcc.
The warnings were already fixed in 16+ by commits 495ed0ef and a9bc04b2
after the _WIN32_WINNT value was increase there. 14 and 13 didn't warn
because they still use a lower value for MinGW, and supported versions
of Visual Studio should compile the code in all live branches but don't
check our format string.
The change doesn't affect the result: sizeof(int) == sizeof(long) on
this platform, and the values are computed with expressions that cannot
exceed INT_MAX so were never interpreted as negative.
Back-patch the formatting change from those commits into 13-15. This
should turn CI's 15 branch green again and stop fairywren from warning
about that on 15.
