I understand that Guido Vollbeding is planning to release a libjpeg at 
release level 7 by the end of the month.  I have been running it here 
on various architecture types without noticing any important issues. 
I do notice that PSNR improves with the updated library.  The 
subsampling algorithm is more advanced so results are not identical to 
JPEG 6b and images re-compressed from the originals may provide better 
quality.

Perhaps Guido can be convinced to include 12-bit symbol naming in the 
new library as well?
