  Sorry, 
yes indeed gcc16 is just one of the machine of the gcc compile farm,
and it is a linux box base on a x86_64 CPU.

Thanks for the approval, patch committed.

  I still didn't really understand this:
  when I run a testsuite with
'make check'.
All individual tests are run from runtest script
which itself uses runtest procedure to execute
each .exp file using the source command.
  Thus I was thinking that the code 
inside each .exp  file was not at global level,
but only at 'runtest procedure level', and I am not even sure
which level that procedure runs.
  Could someone explain to me why we are for sure
at global level when a .exp file is sourced?
