Can't create shared lib on HPUX 10.20 with egcs v1.0.1

[Graham Hudspith]

Dear EGCS,

    Built and installed:

	gcc version egcs-2.90.23 980102 (egcs-1.0.1 release)

    on HPUX 10.20 using './configure --with-gnu-as' with GNU as:
    
        GNU assembler version 2.8.1 (hppa1.1-hp-hpux10.20)

    Can't seem to build a shared library that involves an STL
                                              ^^^^^^^^^^^^^^^
    container (can build shared libraries otherwise).
    ^^^^^^^^^

    The annoying thing is that this works perfectly well under
    GNU v2.7.2.1!

    I would include the makefiles, but these are for an obscure
    (though wonderful, of course) Lucent version of make called 'nmake'.
    
    Originally I had the declaration 'static int_vec my_vec;' inside
    int_add.C, with some access functions to add and get integers
    from this private data structure. This compiled under GNU v2.7.2.1.
    However, when it ceased to compile under egcs v1.0.1, I moved
    the data itself into an unshared file in the feeble hope that this
    would help (it did not). Am I doing something hideously stupid
    here? Or is there a genuine problem? Is GNU v2.7.2.1 wrong?

    Here are some noddy example files:
    
============================= int_vec.h =============================
#include <vector.h>

typedef vector<int> int_vec;

extern int_vec my_vec;

extern int int_add (const int an_int);

============================= int_add.C =============================
#include <int_vec.h>

int int_add (const int an_int)
{
    my_vec.push_back (an_int);

    return 0;
}

============================= make output ===========================

============================= main.C =============================
#include <iostream.h>
#include <int_vec.h>

int_vec my_vec;

int main ()
{
    const int test_int = 42;

    (void) int_add (test_int);

    cout << "Test int = " << test_int;
    cout << ", popped int = " << my_vec[0] << endl;

    return 0;
}
