True. For instance, on the current version of SUSE (10.0), which is 
the distribution I use, the program fails to link unless I uncomment 
the extern "C" lines in jpeglib_namespace.h.

I do not think nested extern "C" blocks are forbidden (but I could not 
find any definitive statement on this in Stroustrup), so I cannot 
think of a reason why the lines cannot be uncommented.

Yes, I agree.
