This is needed to work around a build failure when this test fails, as
it spuriously does when cross-compiling for MinGW using v10 API package,
see https://sourceforge.net/p/mingw-w64/bugs/935/ for more details.
Of course, the fact that the build fails if snprintf() is unavailable is
actually a bug, but in practice this function is available everywhere by
now, so simply stop testing for it.
This mostly cherry picks ceff22ee (Use C99 snprintf, 2021-01-31), but
keeps the test for MSVC versions without vsnprintf() for compatibility.

is only one boolean setting to enable building strtoll() and strtoull()
port functions. The boolean setting enables the necessary port files
to be built, but the remainder of the logic is via pre-processor code
in the common tif_config.h, which was prepared before entering the
port directory to do a build.
directory and add an include path so that the port files can include
tif_config.h. Do not actually include tif_config.h at this time
since CMake and Autotools builds are not prepared for that. This
issue could be handled by updating the CMake and Autotools builds
or by adding a define which directs libport.h to include tif_config.h.
tif_config.vc.h:
Always define HAVE_STRTOL/HAVE_STRTOUL.
Define HAVE_STRTOLL/HAVE_STRTOULL if _MSC_VER >= 1900.
nmake.opt:
Provide defaults suitable for MSVC prior to 14.0.
libport.h:
The sense of the pre-processor logic was inverted from what it
should be. The intention is to only provide the prototype if the
function is missing.

definitions that configure produces, including for WIN64. Still
needs to be tested.
'lld' is not assured by the run-time DLLs and so GCC warns.
Add TIFF_SIZE_T and TIFF_SIZE_FORMAT to provide a type definition
and printf format specifier to deal with printing values of
'size_t' type. In particular, this was necessary for WIN64.
Added a configure test for if the system headers provide 'optarg'
(normal case) and block out the many explicit 'extern' statements
in the utilities. This was found to be necessary under Windows
when getopt is in a DLL and the symbols are already imported with
dllimport via standard header files.
some TIFF/FX support in libtiff. Add the tag definitions to
tiff.h. Add the related TIFF field definitions to tif_dirinfo.c,
and also fixes an error in a comment. Adds the photometric values
to tif_print.c, and fixes a bug. These changes are by Steve
Underwood.
* libtiff/tif_write.c: Fix bug rewriting image tiles in a
the run-time target whereas target is used to specify the final
output target if the package is a build tool (like a compiler),
which libtiff is not. Resolves libtiff bug 2307 "Use
AC_CANONICAL_HOST macro".
* libtiff/tif_fax3.c (Fax3SetupState): Avoid under-allocation of
buffer due to integer overflow in TIFFroundup() and several other
potential overflows. In conjunction with the fix to TIFFhowmany(),
fixes CVE-2010-1411.
* libtiff/tiffiop.h (TIFFhowmany): Return zero if parameters would
result in an integer overflow. This causes TIFFroundup() to also
return zero if there would be an integer overflow.
