And since the VAX days, the image activator is even busier with filling in tons of relocations into the Itanium "short"
section, sharable image symbol-vectors, as well as the references to all the shareable images.

For "fun", I did a ANAL/IMAGE/SEGMENT=DYNAMIC on an XMACRO cross-compiler in my directory.  There are 57237
image relocations just for XMACRO alone.
