>Environment:
System: Linux kiste 2.4.18 #8 Sat Mar 9 15:33:15 CET 2002 i686 unknown
Architecture: i686
GNU ld version 2.13.90.0.4 20020814
host: i686-pc-linux-gnu
build: i686-pc-linux-gnu
target: i686-pc-linux-gnu
configured with: ../gcc/configure --enable-shared --disable-nls --enable-threads=posix --enable-languages=c,c++,f77,objc --enable-__cxa_atexit
>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.
>How-To-Repeat:

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";
}

Compiling thmap.C with -pedantic
