C++ template bug in egcs 1.1.1

[C dot Croughton at alcatel dot de (ccrough tel +711.821. )]

The following program illustrates a problem with template functions which occurs with egcs version 1.1.1 but 
not with the FSF gcc version 2.8.1.

Summary: 
  Using egcs 1.1.1, a friend function in a template is not found by the 
  linker when called from within another template function.  If I call
  the friend function explicitly from a non-template function, it is found,
  or if the calling template function is declared as inline.
  
  Note that the error disappears if any optimisation is used (including
  plain -O; it's there if -O0 is used).

System information:
  gcc version egcs-2.91.60 19981201 (egcs-1.1.1 release)
  GNU ld version 2.9.1 (with BFD 2.9.1)
  Linux sls5tj 2.0.34 #2 Thu Jul 9 10:57:48 EST 1998 i586 unknown
  Pentium Intel 266MHz portable
  
  No arguments to configure when installing egcs.
