>Description:
The following code does no longer compile when -pedantic is given on
the command line. This is a regression with respect to previous
versions of gcc.

source code thmap.C 

#include <ext/hash_map>
#include <ext/rope>

int main()
{
  using namespace std;
  using namespace __gnu_cxx;

  typedef hash_map<char, crope, hash<char>, equal_to<char> > maptype;
  maptype m;
  m['a'] = "42";

Synopsis: Problems with rope and hash_map

State-Changed-From-To: feedback->closed
State-Changed-By: ljrittle
State-Changed-When: Mon Sep 16 20:02:47 2002
State-Changed-Why:
    g++ in -pedantic mode enforces (all/more) requirements
    related to mandatory typename hints.  Patch applied
    to mainline and 3.2 branch (since regression).

 Your patch does fix the problem on my system. I suppose, as you suggest,
 all other occurences of _CAllocator and _SAllocator should be changed in
 the same fashion. Thank you for investigating and fixing the bug.
