-/* This is a workaround for OpenSSL compilation problems when used with <stdint.h>
- * on Windows platforms built with Visual Studio. Including <stdint.h> pulls in
- * <vcruntime.h>, which causes the type size_t to be defined. The size_t type
- * 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 the 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). */
-
-/* In the future libspdm intends to use the Windows native compilation flags and defines,
- * in place of the UEFI profile / personality. */
