you might be using gcc 4.4 on your build box.
gcc 4.4 spits more warnings like what you see. You can do couple of
things. add --disable-werror to gdb recipes but
I would not recommend that. Secondly you can create a patch to gdb/eval.c
Modify line 1644 of gdb/eval.c to
int subscript_array[MAX_FORTRAN_DIMS] = {0};
and this should make gcc 4.4 happy.
