[PATCH] two patches of doubtful usefulness
1)
lpc.c, FLAC__lpc_quantize_coefficients():
This function declares "const int nshift = -(*shift)" variable
when *shift is less than 0. Then nshift is used in the loop:
for(i = 0; i < order; i++) {
error += lp_coeff[i] / (1 << nshift);
This patch adds "const int pshift = *shift" variable.
Pros:
* more symmetry for two branches
* compiler doesn't know that lp_coeff[] and *shift
don't alias, so the code for
error += lp_coeff[i] * (1 << *shift);
is less efficient than for...

Updated CFLAGS patches and make test compilation conditional
Hi Erik,
I've found a middleground for the problem of setting default CFLAGS. I've gone back
to setting them if {C,CXX,CPP,LD}FLAGS are unset at the onset of the configure script
(i.e., the user hasn't specified anything) and then proceed to set them to the defaults
as before. This has been suggested before:

Upstreaming Gentoo patches
Dear FLAC devs,
I would like to get some of our patches merged into master. Most
of them deal with adhering to GNU conventions, respectively not
overriding flags/variables that are up to the user to set. For instance,
honoring $(htmldir) is important, as we have installation paths for the
documentation that differ from what is currently coded in the various
Makefile.am's.
Regards
David
