[libbluray-devel] yes both libs seem fixed in that manner, but libaacs has more problems (MacOSX compile-link problems with libbluray & libaacs ("duplicate symbols"))

Today's git-pull fixed the "duplicate symbol" problem
for both libbluray and libaacs.
[I'm seeing similar on other projects such as
 latest gnupg-2.0.16 now also; none of our pkg-mgrs
 have moved past 2.0.9 here, probably a clue.]

Now today's libaacs has another problem
probably related to ./configure setting
'ac_cv_header_mntent_h=no'
(which I've seen before the dup-syms came about).
I know all this is in infancy.
And I know OSX ain't a Linux system ;) (more like BSD).
So I hacked ./src/libaacs/mmc.c to comment-out
its hard-coded '#include <mntent.h>' on line 29 there
(OSX has no such file).
I don't know what is inside that header file for Linux.
But compiling it this way will result in these:

Doing the regular trouble-shooting,
./configure _did_ successfully find /usr/bin/flex

But in my config.log right underneath the flex test,
we get this:

Then it went on to see -lfl worked,
find 'bison -y' ok,
and continued on.

I guess I need to find the proper headers
for the missing yy* stuff.  :?

For now it won't hurt VLC & MPlayer etc to
not have AACS support, of course
(and me not having any store-bought BDs either <lol>).

I guess I want to help work on this because of what
Steve Jobs says about talking the *AA nuts into
ditching any DRM whatsoever[1], which is why Macs
don't have any official BD support at all, IMO.
[1] as if he can move mountains on this planet.  ;D
I suppose I'd like to prove how open-src can
'solve' this particular dilemma.
We need proper APIs for all this, too,
since Apple stays so secret in meantime.

Thanks for putting up with me.
