egcs-2.90.27 980315 (egcs-1.0.2 release): <string>/-pedantic

[E. Jay Berkenbilt]

I am running a RedHat 5.1/Intel Linux with all updates from RedHat
available as of August 9, 1998.  This includes egcs 1.0.2, gcc
2.7.2.3, and libstdc++-2.8.0.

In this environment, the following C++ source file:

========================================
#include <string>

class A
{
  public:
    A() {};

  private:
    string a;
};
========================================

when compiled with 

g++ -v -c -pedantic a.cc

produces the following output:

GNU assembler version 2.9.1 (i686-pc-linux-gnu), using BFD version 2.9.1.0.4



Editing /usr/include/g++/std/bastring.h to remove the "inline"
qualifier from the operator delete function of the basic_string class
(line 79 in my case) eliminates these errors.

I always use the -Wall -ansi -pedantic when I compile to help me write
code that is as portable as possible.

Please let me know if you need any further information.

this is fixed in the latest egcs snapshot.
