hash_map and -frepo problems

[Greg Galloway <gregg at eoeml dot gtri dot gatech dot edu>]

<hash_map> gives unresolved symbols when used with -frepo.  <hash_map>
works fine when used without -frepo.

Included at the end of this file is a single source file and a Makefile
which builds it four different ways: with and without -frepo; once with
<hash_map>, and once with <map>.

Looking at the ChangeLog for libstc++/stl I see that the same bugs I reported
earlier have been fixed over and over again by several others but keep
getting lost everytime stl is updated to SGI's latest version.  Isn't CVS
supported to allow you to track third party sources like this?

BTW: I get a much smaller set of unresolved symbols when I use the
Moscow Center for SPARC Technology's SGI STL Adaptation.  Their adaptation
also fixes many of the small bugs I've already reported.
