* depends on if _WIN32 or _WIN64 is defined. The default if neither is defined
* is the 32-bit version of size_t. */
/* 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
* if we are compiling as 64-bit. This 32-bit definition then does not agree with
* the 64-bit definition defined in libspdm and generates compile errors. */
/* To workaround this issue, LIBSPDM_OPENSSL_STDINT_WORKAROUND was created
* that is only defined for compilation via tha makefile of the OpenSSL library
* portion of libspdm. */
/* This will lead to _WIN32 and _WIN64 to be NOT defined when reaching the OpenSSL
* portions of a compilation unit (header files + c file), thus meeting the
* no Win32/Win64 requirement for OpenSSL, but will still be defined when compiling
* the <vcruntime.h> file in the compilation unit (and getting the right size_t). */
