Hi all, IMHO the best solution is to define the version of Windows that supports the C compiler before compilation. For example, if your C compiler supports Vista: set HB_USER_CFLAGS=-D_WIN32_WINNT 0x0600
http://msdn.microsoft.com/en-us/library/aa383745%28VS.85%29.aspx Some structures are defined only in the headers from one version of Windows other may change. IPv6 is supported from Windows Server 2003, Windows XP. Even calling functions dynamically is necessary data with which they work. It can make the binary work with earlier versions but the headers and the code should be protected by .- #if _WIN32_WINNT >= 0x0501 ... #endif If not, we can have compile-time errors. Please, what do you think about this, comments? -- Xavi _______________________________________________ Harbour mailing list (attachment size limit: 40KB) Harbour@harbour-project.org http://lists.harbour-project.org/mailman/listinfo/harbour
