/* Our OpenSSL compilation requires _WIN32 and _WIN64 to NOT be defined.
|
|
* This will force the <vcruntime.h> to use the wrong 32-bit definition of size_t
|

|
|
* the 64-bit definition defined in libspdm and generates compile errors. */

|
|
* the <vcruntime.h> file in the compilation unit (and getting the right size_t). */
