[PATCH] treat negative qlp_shift as an error
...;> and in C negative shifts
are undefined.
treat as an error for now to avoid bad behavior but I need to
come back to this to specify exactly."
But libFLAC itself doesn't care about their values. It checks a value
of qlp_coeff_precision, though. So this patch adds a check of
a value of quantization_level.
I'm not sure what should libFLAC do if a negative (=invalid) value of
quantization_level is encountered. But it seems logical that it should
treat an invalid value of quantization_level in the same way as it treats
an invalid value of qlp_coeff_precision.
The patch should also remove "...

Altivec, automake
I think I've gotten FLAC__lpc_restore_signal() about as good as I'm going to
get it.
Here's what I have:
-a new file, lpc_asm.s, which has the assembly routines
-changes to cpu.h, cpu.c, and stream_decoder.c to enable them
-changes to configure.in to support the new cpu stuff
-a preliminary Makefile.am
-maybe something else I'm forgetting
Now automake complains that configure.in
