In libobjc/:
* hash.c: Include objc-private/hash.h instead of objc/hash.h. * objc/sarray.h: Moved into objc/deprecated/sarray.h; objc/sarray.h replaced with a placeholder including the file from the deprecated/ directory. * objc-private/sarray.h: New file (private copy of sarray.h). * hash.c: Include <assert.h> instead of "assert.h" * sarray.c: Include <assert.h> instead of "assert.h". Include objc-private/sarray.h instead of objc/sarray.h. * selector.c: Include objc-private/sarray.h instead of objc/sarray.h. * sendmsg.c: Include <assert.h>. Include objc-private/sarray.h instead of objc/sarray.h. * Makefile.in (OBJC_DEPRECATED_H): Added sarray.h. From-SVN: r164389
