  XCOMM mergelib - merge one library into another; this is commonly used by X
  XCOMM     to add the extension library into the base Xlib.

  XCOMM Create a temp directory, and figure out how to reference the 
  XCOMM object files from it (i.e. relative vs. absolute path names).
  XCOMM
  
  tmpdir=tmp.$$
  origdir=..
  
  XCOMM Remove directory if we fail
  trap "rm -rf $tmpdir; exit 1" 1 2 15
  trap "rm -rf $tmpdir; exit 0" 1 2 13
  
  mkdir $tmpdir
  
  XCOMM Security: if $tmpdir exists before mkdir exit immediately

  XCOMM In the temp directory, extract all of the object files and prefix
  XCOMM them with some symbol to avoid name clashes with the base library.

      mv $i ${objprefix}$i
