It does not exist in any system at present (not even mine): just an idea
in my head to represent the default found at configure time.
In some sense LC_PAPER is set on FC3:
gannet% locale -ck LC_PAPER
LC_PAPER
height=297
width=210
paper-codeset="ISO-8859-1"
and it is unsupported on Solaris 8. And
> Sys.getlocale("LC_PAPER")
[1] "en_GB"
in the system I am prototyping just now.
