Re: [Mingw-w64-public] vsnprintf_s found by default though not present in XP, expected?

[Kai Tietz]

Exactly for such cases we add emulation-code to our libmingwex.a.  To
have it within the .def file for msvcrt is for sure nothing we want.
Instead we should add an emulation-code for it, as we did already for
other such functions.  See in our crt the sec_api folder.

Kai

Yes, I guess the question is (currently the default mechanism can
present executables that don't work on XP, because configure cannot
easily detect the absence of vsnprintf_s) is this desired? Or if that
ship has sailed, that's OK too.

That was because the 'libmsvcrt.a' library was created using a new version of 
MSVCRT.DLL which exported the function, but the MSVCRT.DLL shipped with Windows 
XP didn't.

主题：[Mingw-w64-public] vsnprintf_s found by default though not present
in XP, expected?

As a note, if configure scripts today look for
vsnprintf_s
they find it "present"
however, this causes
“the procedure entry point _vsnprintf_s could not be located in the
dynamic library msvcrt.dll”
on XP boxes.  Just calling it out in case this is expected or not, as
it somewhat surprised me.

$ grep vsnprintf_s . -r
Binary file ./cross_compilers/build/crt/lib64/libmingwex.a matches
Binary file ./cross_compilers/build/crt/lib64/libmsvcrt.a matches

Thanks all.
