Sorry, hit enter too soon.  It seems that inside of a templated function call, a
templated member function will make it think it's a syntax error.  This work
fine in RHEL4, but does not in RHEL3, with the newest gcc-c++ and libraries.

Error:

[root@linuxdevhq01 test]$ g++ test.cpp
test.cpp: In function `void f()':
test.cpp:13: syntax error before `>' token


Code:

#include <iostream>

struct Object {
  template <typename T>
  T* g() {
    return NULL;
  }
};

template <typename T>
void f() {
  Object o;
  T* d = o.g<T>();
}

int main() {
  f<int>();
  return EXIT_SUCCESS;
}

Please use
T* d = o.template g<T>();
instead in RHEL3.
While this is not mandatory in C++, this is one of the several problems that
can't be fixed easily (and safely) in the old C++ parser.  In G++ 3.4.0 the
C++ parser has been rewritten and this rewrite made it far more ISO C++
compliant.
