problems in linking

["P.S.Ravi Kiran" <psrk at cdotb dot ernet dot in>]

hai,

        I am Ravi Kiran, a Research Engineer from c-dot India. 
I am woking on linux platform and I have to export my code
to a Mc68302 basedcard. So I got the bin-utils,gcc,newlib as you said
in
the webpage, and compiled for the target m68k-elf.
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........
