libgcj.so: undefined reference to `ip'

Hi, guys.

I'm compiling gcc-4.4.2 on arm similar platform and getting a fail
during the link stage.
Using command `nm' to read symbols in libgcj.so, i find the symbol
`ip' is undefined.
I grep the libjava directory, but cannot find the definition for `ip'.
Could someone tell me where its definition and use which library to
resolve the reference in libgcj.so?
