MIPS64 build questions

Waldemar,
I have been building uclibc on 32 bit mips for a while but I only looked
at the MIPS64 uclibc build after I saw your email. I haven't been
able to build for MIPS64 N32 or N64 ABI's yet and I was wondering if you
have run into either of the problems I am seeing.
I am using the latest sources with your patch included.
For MIPS64 and the N32 ABI my build dies with:
libc/sysdeps/linux/mips/pread_write.c:23:32: error: '__NR_pwrite' undeclared (first use in this function)
# define __NR___syscall_pwrite __NR_pwrite
^
/local/home/sellcey/gcc/uclibc/obj-mips-mti-linux-uclibc/uclibc/obj_mips64/include/bits/syscalls.h:157:4: note: in definition of macro 'internal_syscall4'
: input, "r" (__a0), "r" (__a1), "r" (__a2) \
^
/local/home/sellcey/gcc/uclibc/obj-mips-mti-linux-uclibc/uclibc/obj_mips64/include/bits/syscalls-common.h:15:33: note: in expansion of macro '__NR___syscall_pwrite'
# define SYS_ify(syscall_name) (__NR_##syscall_name)
.
.
.
On MIPS64 with the N64 ABI it dies with:
/local/home/sellcey/gcc/uclibc/obj-mips-mti-linux-uclibc/uclibc/obj_mips64_64/libc/libc_so.a(lockf64.os): In function `lockf64':
lockf64.c:(.text+0x88): undefined reference to `fcntl64'
collect2: error: ld returned 1 exit status
make: *** [/local/home/sellcey/gcc/uclibc/obj-mips-mti-linux-uclibc/uclibc/obj_mips64_64/lib/libc.so] Error 1
Have you seen either of these errors in any of your builds?
