Bug ID: 108203
Summary: Format string checking with __USE_MINGW_ANSI_STDIO
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: nightstrike at gmail dot com
Target Milestone: ---
Circa v4.5, some mingw-w64 users discovered an issue with printf functions and
g++. Addressing this resulted in a kludge on the mingw-w64 headers side, but
this should have been documented here so that we can remove the kludge and have
a better coordination between projects.
Original mail thread describing the problem:

+/* Override __builtin_printf-routines ... Kludge for libstdc++ ...*/
+#define __builtin_vsnprintf __mingw_vsnprintf
+#define __builtin_vsprintf __mingw_vsprintf
I hope with this PR, we can better coordinate and make both sides better :)
