Chiefly because its removal is being considered for systems where unexec never posed a problem: Solaris (where unexec is an OS feature and virtually the recommended solution for such requirements as saving the state of a program to disk), DJGPP, where you implemented specific support for unexec in the C library, and suchlike. I'm not so implacably opposed to removing it for Windows, provided that its successor is made to function on Windows 98, or the machines where it is wanted disappear.
