c++/5390: Libiberty fails to demangle multi-digit template parameters.

[Wolfgang Bangerth]

Carlo,
first this: When I complained that this PR has been sitting idle despite 
the fact that it has a patch, I complained to the ones who are in power of 
reviewing and applying patches. That it has not been reviewed is not your 
fault. We are grateful for people sending in patches, and I, too, am 
embarrassed if we turn them down by just not taking notice of their 
work...

As time progresses, this is becoming more and more irrelevant: as far 
as I understand you,
- gcc since 3.0 has a different mangling scheme, which isn't concerned in 
  this PR 
- gcc up to 2.95 has never generated the cases that your patch addresses
- gcc 2.95 is certainly not going to be fixed to generate them any more
- gcc 2.95 is slowly dying out.

The question thus is: if people are not overly interested in your patch 
(which is regrettable, but apparently the case), then we can as well close 
the PR. Since if we don't, we'll ask the same question again in a year, 
and then people will care even less about 2.95.

What's your opinion on this?

Thanks
  Wolfgang
