ruby--ruby/internal.h
akr 70232e400c * process.c (proc_exec_v): don't call dln_find_exe_r here because it
is not async-signal-safe and proc_exec_v is called in a child
  process.
  command_abspath field of rb_exec_arg.
  (rb_exec_fillarg): call dln_find_exe_r and set command_abspath.
  (rb_exec_err): Give the absolute path of the invoking command for
  proc_exec_v, instead of the command name.

* internal.h: add command_abspath field for rb_exec_arg.
