Really?  Not for me:

  % ~/installs/bison/2.3a/bin/bison --skeleton="/tmp.m4" tmp.y
  /usr/local/bin/m4: /home/jdenny/installs/bison/2.3a/share/bison//tmp.m4: No 
such file or directory
  /home/jdenny/installs/bison/2.3a/bin/bison: subsidiary program 
`/usr/local/bin/m4' failed (exit status 1)

  % ~/installs/bison/2.3a/bin/bison --skeleton="./tmp.m4" tmp.y
  /usr/local/bin/m4: /home/jdenny/installs/bison/2.3a/share/bison/./tmp.m4: No 
such file or directory
  /home/jdenny/installs/bison/2.3a/bin/bison: subsidiary program
