No need to cast to char * now that all supported platforms use C89-standard void * argument types, so just drop the casts from acmp & acopy macros, which clears the gcc warnings for places const pointers were cast non-const: access.c: In function 'DefineSelf': access.c:786:3: warning: cast discards qualifiers from pointer target type access.c:795:6: warning: cast discards qualifiers from pointer target type access.c: In function 'NewHost': access.c:1293:9: warning: cast discards qualifiers from pointer target type access.c:1298:6: warning: cast discards qualifiers from pointer target type access.c:1309:5: warning: cast discards qualifiers from pointer target type Without the casts, acmp & acopy are just a funny way to write memcmp & memmove, so drop the macros and inline the calls, taking care to swap the first two arguments to memmove since it had swapped them. Since all the calls to memmove end up being to non-overlapping memory (mostly copying from an existing pointer to a newly allocated one), replace those with memcpy. And finally, don't actually call memcpy to copy 0 bytes from one place to another, since that's just a waste of a perfectly good function call.

X Server
The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.
Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.
