Hello,

I recently attempted to compile Octave from CVS and ran across the following problem:

 I checked in file-io.cc and gplot.cc and tmp_files is declared twice.

 file-io.cc:
 104  // List of files to delete when we exit or crash.
 105  //
 106  // XXX FIXME XXX -- this should really be static, but that causes
 107  // problems on some systems.
 108  std::stack <std::string> tmp_files;



 gplot.cc:
 2000  // List of files to delete when we exit or crash.
 2001  //
 2002  // XXX FIXME XXX -- this should really be static, but that causes
 2003  // problems on some systems.
 2004  std::stack <std::string> tmp_files;


 Commenting out line 2004 in gplot.cc allows it to compile.
