I've been trying to build GNU emacs (version 17) on my ICM 3216 (SysV). I can't
get unexec to work and the reason seems to be that there is a hole in the
virtual address space of executables produced by ld.

The hole is between the .text and .data segments. Its size varies depending
on the size of .text (presumably) but it is NOT just the gap to the next
page boundary.

Is this a bug? Admittedly the wasted virtual address space would not normally
be a problem. Interestingly the .data segment doesn't start on a page boundary.

There is ld -N but that has the undesirable side effect of making the text
segment unsharable.
