I get the following text when I try to compile the included file: g++ -O3 -Wall -I. -c -o log10_linear.o log10_linear.c log10_linear.c: In function `int fm_log10_v_linear(float *, float *, int)': log10_linear.c:187: Internal compiler error: log10_linear.c:187: Internal compiler error in `convert_move', at expr.c:570 Please submit a full bug report.

Thanks very much for your efforts, Dave.
