On my platform (Fedora 19 x86-64), this shrinks the Emacs executable (text+data) by 0.25%. * dispextern.h (erase_phys_cursor) [!WINDOWSNT]: (load_color) [!MSDOS]: * gnutls.h (emacs_gnutls_transport_set_errno) [!WINDOWSNT]: * keyboard.h (make_ctrl_char) [!WINDOWSNT]: * lisp.h (check_existing): * process.h (conv_sockaddr_to_lisp, network_interface_list) (network_interface_info) [!WINDOWSNT]: * termhooks.h (encode_terminal_code) [!WINDOWSNT]: Remove extern decls. * fileio.c (check_existing): * keyboard.c (make_ctrl_char) [!WINDOWSNT]: * process.c (conv_sockaddr_to_lisp, network_interface_list) (network_interface_info) [!WINDOWSNT]: * term.c (encode_terminal_code) [!WINDOWSNT]: * xdisp.c (erase_phys_cursor) [!WINDOWSNT]: * xfaces.c (load_color) [!MSDOS]: Now static. * fileio.c (check_existing, check_executable, check_writable): * process.c (network_interface_list, network_interface_info): Move earlier, so that we don't need forward decls. * gnutls.c (fn_gnutls_transport_set_errno) (emacs_gnutls_transport_set_errno) [!WINDOWNT]: Remove; unused. * w32.c (init_environment): Use faccessat rather than check_existing, partly for consistency with the rest of the code in this file, partly so that check_existing can be static.
