This removes an assumption that EMACS_INT and long are the same width as pointers. The assumption is true for Emacs porting targets now, but we want to make other targets possible. * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX. (EMACS_INTPTR, EMACS_UINTPTR): New macros. In the rest of the code, change types of integers that hold casted pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically replacing EMACS_INT, long, EMACS_UINT, and unsigned long. (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed. (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here. No need to cast type when ORing. (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR. * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast. * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to assume EMACS_INT is the same width as char *. * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb): (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item): Remove no-longer-needed casts. (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback): (xg_tool_bar_help_callback, xg_make_tool_item): Use EMACS_INTPTR to hold an integer that will be cast to void *; this can avoid a GCC warning if EMACS_INT is not the same width as void *. * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast. * xdisp.c (display_echo_area_1, resize_mini_window_1): (current_message_1, set_message_1): Use a local to convert to proper width without a cast. * xmenu.c (dialog_selection_callback): Likewise.
