The following error occurs in stage2:

insn-output.c: In function `output_188':
insn-output.c:790: error: `asm_out_file' undeclared (first use in this function)
insn-output.c:790: error: (Each undeclared identifier is reported only once
insn-output.c:790: error: for each function it appears in.)
insn-output.c: In function `output_189':
insn-output.c:801: error: `asm_out_file' undeclared (first use in this function)

Looking at the preproccessed source for insn-output.c, I see the following:

# 385 "../../gcc/gcc/output.h"
extern FILE *asm_out_file;
...
static const char *
output_44 (rtx *operands __attribute__ ((__unused__)), rtx insn __attribute__ ((
__unused__)))
{

{
  rtx xoperands[3];
  extern FILE *asm_out_file;
...
static const char *
output_45 (rtx *operands __attribute__ ((__unused__)), rtx insn __attribute__ ((
__unused__)))
{

{
  rtx xoperands[3];
  extern FILE *asm_out_file;
...
static const char *
output_188 (rtx *operands __attribute__ ((__unused__)), rtx insn __attribute__ (
(__unused__)))
{

{
  output_asm_insn ("bl .+8,%0\n\tdepi 0,31,2,%0", operands);
  (*targetm.asm_out.internal_label) (asm_out_file, "L",
                                     (((operands[1])->u.fld[6]).rtint));
  return "";
}
}
...

If I remove the declations of asm_out_file from output_44 and output_45,
the file compiles.  These declarations appear to be reminants from an
earlier time when output.h was not included.

It seems a declaration in an inner scope now causes an earlier declaration
at file scope to be forgotten.
