Are you sure you want --enable-64?  Did you note the warning issued by
configure when you use it?

BTW, instead of

  F77="..." CFLAGS="..." ...  configure --other-options ...

it is generally best to use

  configure F77="..." CFLAGS="..." ... --other-options ...

because then the values of these variables are recorded in the
config.status file.

This looks like a bug in something other than Octave.  What package does
the file

  /ifi/fenris/a05/fl/work/OPTERON/usr/local/include/proto.h

belong to?

Please try the following patch and let me know if it allows you to get
past this problem.
