100 * Microsoft's C Runtime library is missing strcasecmp and strncasecmp.

102 * There is no symbol uniquely defined in Microsoft's header files that
103 * can be used by the preprocessor to know whether we're compiling for
104 * Microsoft's library or not (or which version). Thus there's no
105 * way to automatically decide whether or not to define strcasecmp
106 * in terms of stricmp.
107 *
108 * The Microsoft *compiler* defines _MSC_VER. On the assumption that
109 * anyone using their compiler is also using their library, the below
110 * tests check _MSC_VER as a proxy.
