Introduce SYS_FUNC macro to declare and define all syscall parsers. * Makefile.am (BUILT_SOURCES, CLEANFILES): Add sys_func.h. (sys_func.h): New rule. * defs.h (SYS_FUNC_NAME, SYS_FUNC): New macros. * linux/syscall.h: Include "sys_func.h". [NEED_UID16_PARSERS]: Use SYS_FUNC to declare uid16 syscall parsers. Remove other declarations. * linux/alpha/syscallent.h (160, 161): Add sys_ prefix to osf_statfs and osf_fstatfs syscall parsers. * *.c: Use SYS_FUNC to define syscall parsers.
