 Well - it's not "part of the linker" as much as part of the link
step; you need to find some library to link with that defines this.

 Fortunately many such libraries exist, particularly for Windows95
and Win/NT.  In particular, for "free-ish" offerings; we've had
amazing good luck with the Cygnus effort (it's GPL'd) - see
http://www.cygnus.com.
