On Windows outside of gcc, assembly source is normally named *.asm.  R 
only uses one assembly source file named *.S so I think it's fairly 
unlikely that this will cause confusion.  I don't know if it's more 
common on OS X.

On the other hand, *.s or *.S are reasonably common names for S source 
files in packages, so I think this is a useful change, at least in Windows.
