Hi all, Attached is a patch to allow the current version of Emacs in CVS to compile on Tiger. It was suggested [1] to comment out sys_select() and select_and_poll_event() in sys/mac.c. This is a bad idea, on my system it results in an Emacs that eats up 100% of the CPU. Instead, my patch reorders the includes in sys/mac.c so that things work out fine. Best, Ciamac. 1.
