`__NR_vfork' undeclared

["Jack Howarth" <howarth@bromo.med.uc.edu>]

    Has anyone else run across this problem on glibc 2.1.1pre1. In building
the strace 3.1 on linuxppc (egcs 1.1.2, binutils 2.9.1.0.22b, Linux 2.2.4 and
glibc 2.1.1pre1) I am now finding a compile failure of...

gcc -b ppc-redhat-linux -Wall -DHAVE_CONFIG_H   -I. -Ilinux/ppc -I./linux/ppc -Ilinux -I./linux -O2 -fsigned-char -c syscall.c
syscall.c: In function `internal_syscall':
syscall.c:489: `__NR_vfork' undeclared (first use in this function)
syscall.c:489: (Each undeclared identifier is reported only once
syscall.c:489: for each function it appears in.)
make: *** [syscall.o] Error 1

...which seems very odd since the header syscall.h in /usr/include/bits
has..

#define SYS_vfork __NR_vfork

the /usr/include/sys/syscall.h indicates that the linux headers should
provide these? Unfortunately I don't see this declared anywhere in
/usr/include/linux. Is anyone seeing this on other platforms?
