Disable some msvc "deprecated function" warnings again

In addition to removing the inline #define, commit 209849a4 also
removed a #pragma to disable msvc deprecated function warnings.
Without this #pragma, msvc currently issues 19 warnings related
to "deprecated insecure c-library functions", such as strcpy()
and 22 warnings related to "deprecated POSIX function names",
such as open().

In order to supress these warnings, re-instate the #pragma.
