mpeglib inlining fixes (sorry, no diff, complete sources)

I contacted the mpeglib author, mvogt@rhrk.uni-kl.de, on 2002/08/25 with
this problem, but didn't get any reply, neither was the bug fixed as it
seems. Original mail to above address follows:

--------
Hi,
please change all inline assembly labels from "<label>" to "<label>_%=" to
prevent duplicate symbol errors caused by inlining due to optimization
flags. "%=" generates a unique number per instance and thus inlining
becomes possible.

Example:

label: movl %eax,(%ebc,%ecx,4)
       decl %ecx
       jnz  label

The above is impossible with inlining as there are multiple instances of
"label" defined. This is fixed below:

label_%=: movl %eax,(%ebc,%ecx,4)
	  decl %ecx
	  jnz label_%=

Now every inlined instance has a unique label and thus inining is possible.
--------

Just replace two files with the ones in the attached archive (sorry, no time
for a unified diff right now) to get rid of this bug.
