  Oops, when I did the VSTa support for cross compiling I never tested
G++. Down in gcc/config/i386/vsta.h is:

#undef EXTRA_SECTIONS
#define EXTRA_SECTIONS in_ctor, in_dtor

#undef EXTRA_SECTION_FUNCTIONS
#define EXTRA_SECTION_FUNCTIONS \
  CTOR_SECTION_FUNCTION \
  DTOR_SECTION_FUNCTION

#define CTOR_SECTION_FUNCTION \
void \
ctor_section () \
{ \
  if (in_section != in_ctor) \
    { \
      fprintf (asm_out_file, "\t.section .ctor\n"); \
      in_section = in_ctor; \
    } \
}

#define DTOR_SECTION_FUNCTION \
void \
dtor_section () \
{ \
  if (in_section != in_dtor) \
    { \
      fprintf (asm_out_file, "\t.section .dtor\n"); \
      in_section = in_dtor; \
    } \
}

  You might want to remove this. VSTa uses a.out, and that object file
format (like old sun3's) only support three sections, namely .text, .data
and .bss. For a.out I usually stick the ctor and dtor tables in .text.
