Summary:  WDCE used in wdt.h for device which doesn't have the bit in WDTCR

Original Submission:  Found the following bug during compile of watchdog 
related code on ATmega32 using wdt.h version:
/* $Id: wdt.h,v 1.9 2004/11/08 23:52:28 arcanum Exp $ */
from avr-libc v1.2.0

Both macros _wdt_write(value) using the WDCE bit:

: /* no outputs */  
: "I" (_SFR_IO_ADDR(_WD_CONTROL_REG)), 
"r" (_BV(WDCE) | _BV(WDE)), 

it's OK for device which WDCE bit, but not for example the ATmega32.
The code will compile with error: `WDCE' undeclared...

The mega32 has the WDTOE bit in place of the WDCE bit. This bit name needs to 
be abstracted in wdt.h.
