#61 Blending with 16-bit YUVA/RGBA colormodes broken in 1.1

When Cinelerra 1.1 + associated utilities are
compiled from sources using GCC 3.1.1 and
recommended CFLAGS, the 16-bit RGBA and
YUVA models do not work properly. When
blending needs to be done between tracks, the
color information seems to be lost, destroying
the composited output. Screenshots are
attached to provide a visual description of the
problem.

System setup: AMD Athlon Thunderbird 850,
Gentoo Linux 1.3, GCC 3.1.1, glibc 2.2.5.

Cinelerra compiled with CFLAGS:

-O3 -march=i686 -fmessage-length=0
-funroll-all-loops -fomit-frame-pointer
-falign-loops=2 -falign-jumps=2
-falign-functions=2

(The flags -malign-[loops,jumps,functions] were
deprecated in GCC 3.1.1.)

    This PNG shows what occurs when rendering in YUVA 16-bit mode. A second file will be attached that shows the correct blending.

    This PNG shows the correct output, using YUVA 8-bit mode.
