It's FreeSpire (the free version of Linspire, formerly Lindows), which is
based on Debian pre-Etch.

That'd be fine if only the external declaration is provided by libreplace.  My
understanding was that libreplace provided functions that are needed but not
available on the system.  This is a different problem, in that the system
provides the function (which is why the original configure test passed) but no
header file declares the function, so the compile fails.

Are there cases already handled by libreplace where it provides only an
external declaration where one isn't provided by the system?  If so, that'd be
the way to go and could be easily cloned.  The downside of doing it this way
is that it requires adding to libreplace every time any system is found to
have a missing system declaration.
