On some platforms, detection of memset_s() and defining HAVE_MEMSET_S might need user to run CPPFLAGS=-D__STDC_WANT_LIB_EXT1__=1 ./configure ... for make, or similar for SCons, CMake

As you said yourself __STDC_WANT_LIB_EXT1__ should also be used in the configure step.

Would you like me to add -D__STDC_WANT_LIB_EXT1__=1 to CPPFLAGS in configure.ac and to add_definitions in src/CMakeLists.txt and autoconf.env.Append(CPPFLAGS = ... in SConstruct?

committed in 51e0f208 to add define to first.h

Depending on feedback from those using memset_s() on their platforms, we might need to additionally modify detection logic during build configure time.
