>Description:
stl_alloc.h does not #include <bits/stl_config.h> and as a result does
not have the macro __STL_VOLATILE available to it.  This causes a
parse error at compile time for legal code which uses the STL.

>How-To-Repeat:

iostream.h is a good example of a header whose inclusion triggers the
problem.  With a newly-bootstrapped gcc, I compile hworld2.cpp:

#include <stdio.h>
#include <iostream.h>
int main(int argc, char **argv)
{
printf("Hello, World!\n");
}

As with many parse problems I get a huge pile of errors, the first and
only relevant of which is:

In file included from /usr/local/include/g++-v3/bits/std_memory.h:21,
                 from /usr/local/include/g++-v3/bits/std_string.h:43,
                 from /usr/local/include/g++-v3/bits/localefwd.h:42,
                 from /usr/local/include/g++-v3/bits/std_ios.h:43,
                 from /usr/local/include/g++-v3/bits/std_ostream.h:39,
                 from /usr/local/include/g++-v3/bits/std_iostream.h:40,
                 from /usr/local/include/g++-v3/backward/iostream.h:32,
                 from hworld2.cpp:2:
/usr/local/include/g++-v3/bits/stl_alloc.h:259: parse error before `[' token

(I get one of these for every appearance of the __STL_VOLATILE macro in
stl_alloc.h)

>Fix:

This is trivially fixed by adding:

#include <bits/stl_config.h>

near the beginning of stl_alloc.h; with this change, my hworld2.cpp
compiles and runs perfectly.
