problems in linking

[P.S.Ravi Kiran]

gcc version   - 2.95.2 
binutils      -2.9.1 
newlib        -1.8.2

configuration options--  from config.status file 
../src/configure 
--with-gcc-version-trigger=/home/psrk/temp/src/gcc/version.c
--host=i686-pc-linux-gnu --target=m68k-coff --prefix=/home/psrk/m68k -v
--norecursion

I got the binaries correctly and also I could compile my files
well. but when linking, it is giving the following errors in 
the compiler sources.

/home/psrk/temp/build/m68k-coff/libgloss/m68k/../../../../src/libgloss/m68k/../open.c:28:
undefined reference to `__errno'
/home/psrk/m68k/m68k-coff/lib/libidp.a(lseek.o): In function `lseek':
/home/psrk/temp/build/m68k-coff/libgloss/m68k/../../../../src/libgloss/m68k/../lseek.c:28:
undefined reference to `__errno'

can u please tell me what I can do with that error ?




And also there is one more problem that I have a function 
written in C like this.

int disable()
{
  register temp;
  asm(" move.w %sr,temp");
  asm(" andi   #61695,%sr");
  return(temp);
}

The compiler is not giving any warning, but the linker says 
"undefined refarence to temp " in the asm statement.
I tried with _temp and it says
"undefined refarence to _temp "


I have some more functions written in assembly that the linker
was un-able to link them to C functions.



So please help me  in resolving these 

Thank you......
bye........
