[Bug-gnulib] Multiple definitions of symbol _xalloc_die

[Simon Josefsson]

I'm now using the xalloc-die approach on two of my libraries, GSS and
Shishi.  But MacOS X doesn't seem to like this (see link error below).

The Shishi version is:

/* If non-NULL, call this function when memory is exhausted. */
void (*shishi_alloc_fail_function) (void) = 0;

void
xalloc_die (void)
{
  if (shishi_alloc_fail_function)
    (*shishi_alloc_fail_function) ();
  fflush (stdout);
  fprintf (stderr, _("%s: Memory allocation failed\n"), PACKAGE);
  abort ();
}

And the GSS version is:

/* If non-NULL, call this function when memory is exhausted. */
void (*gss_alloc_fail_function) (void) = 0;

void
xalloc_die (void)
{
  if (gss_alloc_fail_function)
    (*gss_alloc_fail_function) ();
  fflush (stdout);
  fprintf (stderr, _("%s: Memory allocation failed\n"), PACKAGE);
  abort ();
}

Do you know if there is a solution to this?

I guess I could AC_DEFINE([xalloc_die], [gss_xalloc_die]) or
something.

Hm.  Should the xalloc_die's be static?  But then libgnu.la wouldn't
find it, right?

Thanks.
