Learn what .S means?  For some reason you tried to compile .s*, and 
although that happens to match on your benighted OS, .s and .S are not 
the same.

I have no idea why you are asking here.  That file is not part of R 
and you have not told us where you found it.  There is a file of that 
name as part of a *copy of xzutils* shipped with the R sources, and R 
compiles it correctly: and you can read the sources for yourself to 
see how it does it.
