Indeed.

For gcj, could someone arrange to include a special object at the
beginning and end of each library or executable?
Something like:
-----------------------------------------------------------------
int __attribute__((__visibility__("hidden"))) _Jv_datastart = 1;
int __attribute__((__visibility__("hidden"))) _Jv_bssstart;
extern int _Jv_dataend;
extern int _Jv_bssend;
static void __attribute__((__constructor__))
_Jv_RegisterDataSegments (void)
{
 extern void GC_add_roots (void *, void *);
 GC_add_roots (&_Jv_datastart, &_Jv_dataend);
 GC_add_roots (&_Jv_bssstart, &_Jv_bssend);
}
----------------------------------------------------------------
