I just tried to compile package xplanet-1.2.0-46
with the new GNU compiler version 4.3 snapshot 20070126

The compiler said

jpleph.cpp:615: warning: array subscript is above array bounds

The source code is

   for( i = 0; i < 3; i++)
      rval->ipt[12][i] = rval->ipt[12][i + 1];

but

	long ipt[13][3];

so the program is trying to index 4 into an array of size 3.

Suggest code rework.
