 ^^^^^^^^^^
There's a clue... pow(double, int) is supposed to be declared as an
inline C++ function, not a C function.
The header libjava/java/lang/mprec.h includes <math.h> from within a
`extern "C" {...}' block... that looks wrong to me. (Are nested "C"
blocks even allowed in C++?)
Try the patch below and let us know if it works. (BTW the warnings
about __malloc__ indicate your gcj compiler is out-of-date.)
