10 # not contain these strings, add -DSTRIP_FBSDID (see <sys/cdefs.h>) to CFLAGS
11 # below. Note: there are no IDs for syscall stubs whose sources are generated.
12 # To include legacy CSRG sccsid strings, add -DLIBC_SCCS and -DSYSLIBC_SCCS
13 # to CFLAGS below. -DSYSLIBC_SCCS affects just the system call stubs.
