template friend error in 19980502

["Hugh W. Holbrook" <holbrook at dsg dot stanford dot edu>]

This worked in 1.0.2 but doesn't in 19980502.  Apologies if this is a
duplicate.

Thanks for all of your great work.  Egcs is a great tool.

/* 
   This program produces the following error when compiled with 19980502
        $ c++ -c test.cxx
        test.cxx:17: redefinition of default argument for `class Hash'

        gcc version egcs-2.91.26 19980502 (gcc2 ss-980401 experimental)

   The friend declaration appears to be the culprit.
   Removing it makes the problem disappear.
        $ c++ -c test.cxx -DMAKE_IT_WORK
        $

   This compiles without error on 1.0.2.
