[PATCH] fix dbxout.c bootstrap failure on rs6000-aix

[Olivier Hainque <hainque at adacore dot com>]

Hello,

Boostrapping a recent trunk on powerpc-ibm-aix5.3.0.0 fails in stage2
with

  cc1: warnings being treated as errors
  .../src/gcc/dbxout.c:3393: error: 'dbxout_block' defined but not used
 
which looks legitimate to me. dbxout_block and a number of associated
helpers are only referenced #if defined (DBX_DEBUGGING_INFO), and
their definition is not so restricted.

The attached patch fixes that by arranging to have the definitions and
associated declarations conditioned the same way as the references, that is,
within an #if defined (DBX_DEBUGGING_INFO) block.

Tested by checking that the bootstrap proceeds past the failure point
after the change.

	* dbxout.c (dbxout_block): Move declaration within the first
	#if defined (DBX_DEBUGGING_INFO) block.  Rearrange another such
	block to include the definition, together with the associated
	helpers.
