| * The _WIN32_WINNT is described here: |
| * https://learn.microsoft.com/en-us/cpp/porting/modifying-winver-and-win32-winnt?view=msvc-170 |
| * In a nutshell the macro defines minimal required Windows version where |
| * the resulting application is guaranteed to run on. If left undefined here, |
| * then the definition is provided by the Windows SDK found on host where |
| * application is being built. |
| * |
| * OpenSSL defaults to version 0x501, which matches Windows XP, meaning the |
| * compiled library will use APIs available on Windows XP and later. User may |
| * override the version specified here at build time using command as |
| * follows: |
| * perl ./Configure "-D_WIN32_WINNT=0x...." ... |
| * |
| * The list of recognized constants (as found in the link above) is as follows: |
| * 0x0400 // Windows NT 4.0 |
| * 0x0500 // Windows 2000 |
| * 0x0501 // Windows XP |
| * 0x0502 // Windows Server 2003 |
| * 0x0600 // Windows Vista, Windows Server 2008, Windows Vista |
| * 0x0601 // Windows 7 |
| * 0x0602 // Windows 8 |
| * 0x0603 // Windows 8.1 |
