Here is the patch I came up with to address the getc_unlocked problem.
The problem is that HAVE_GETC_UNLOCKED is true (because HP-UX has it)
but the declaration isn't seen because we didn't compile with
-D_REENTRENT, thus we get a no-declaration error.  Tested on IA64 HP-UX.


binutils/ChangeLog:

2005-05-05  Steve Ellcey  <sje@cup.hp.com>

	configure.in: Check for getc_unlocked prototype.
	configure: Regenerate
	config.in: Regenerate
	strings.c: Only call getc_unlocked if we have seen a prototype.
