At first I thought it could be my setting CFLAGS in RPM build process, so I
allowed MPlayer's configure to choose it's own, but to no avail. And I
thought I reported something similar recently and someone said it was
fixed...

BTW: funny thing, which I never noticed before because I always
set CFLAGS manually. Well, two things, actually.
One: as you can see above, configure chooses -march=i486 -mcpu=i686 for
OPTFLAGS even though my CPU is a Duron and is detected:
[...]
Checking for gcc3 version ... 3.1, ok
Checking for CPU vendor ... AuthenticAMD (6:3:1)
Checking for CPU type ...  AMD Duron(tm) processor
Checking for GCC & CPU optimization abilities ... athlon
[...]
Two: some of the subdirs' Makefiles don't include -Wall in CFLAGS, so lots
of warnings go unnoticed. I recently added -Wall to my manually-set CFLAGS
and suddenly warnings log jumped from 700 bytes to 18k bytes. I'll try to
make a patch next week, when I'm back (going home for the Day of the Dead).
