typedef vs. typename confusion

[Fred Richardson <frichard at bbn dot com>]

Hi-

I have some older template code (which is too big to paste here) which
used to compile and run with egcs-1.0.3 but breaks with the following
version of egcs off the 1.1 CVS branch:

  % gcc -v
  Reading specs from /d4mutl/bybrad.dev/lib/gcc-lib/i686-pc-linux-gnulibc1/egcs-2.91.52/specs
  gcc version egcs-2.91.52 19980802 (gcc2 ss-980609 experimental)
  %

The problem I found is that if I neglect to use typename in certain
places, the compiler will get confused and use a different (and on my
part unspecified) set of template parameters (currently for or in a
friend function) and complain that no match can be found for the
function I'm calling.  Usually the function(s) it lists in the
possible matches have parameters for classes that I never instantiated 
or specified anywhere else in the code.

I've been trying to come up with a small example, but I haven't been
able to.  I have a pretty complicated template class hierarchy that
triggers this problem.  I'll keep chiseling away at it, but I was
wondering if anyone else has seen this problem.
