[patch][c++] fix "invalid conversion from ‘void*’ to ‘char*’"

[Irfan Adilovic <irfanadilovic@...>]

In the 5.3.3 release, lua/lstrlib.cc:936:

    char *ppoint = memchr(buff, point, nb);

is not valid c++ code. This should be fixed with a c-style cast:

     char point = lua_getlocaledecpoint();  /* try locale point */

-    char *ppoint = memchr(buff, point, nb);

+    char *ppoint = (char *)(memchr(buff, point, nb));

     if (ppoint) *ppoint = '.';  /* change it to a dot */
