Hi,
One of our users tried to run a Qt5 based application on Windows XP and
Windows Server 2003, but stumbled across a fatal error indicating that
the symbol vsprintf_s isn't available in msvcrt.dll [1].
After searching I've found out that the msvcrt.def.in still contains a
reference to vsprintf_s even though there's a wrapper implementation of
this symbol in mingw-w64-crt/secapi/vsprintf_s.c so it shouldn't be
mentioned in the msvcrt.def.in file any more.
After testing some more (see testcase at [2]) I also discovered some
other issues with the secapi wrappers. The attached patches should fix
these.
Regards,
Erik van Pienbroek

Subject: [PATCH 2/2] Remove rand_s and vsprintf_s from msvcrt.def.in
These symbols are implemented in the secapi wrappers so they
shouldn't be part of the msvcrt.def.in files any more
