Looks like I jumped the gun on this. Looks like we will be deprecating the 
macros. See this thread on the mailing list for more details:

Summary:  I read from phorum that outb() is deprecated? But still can found a 
note from library "Use outb() in new programs".

Original Submission:  I'm not sure if I am right (still uncertain), but I read 
from avrfreaks phorum that outb() is deprecated. I know that outp() is 
deprecated, but I can't find such mention of outb(). I find such mentions 
(introduced below) on chapter "5.16 Special function registers".

PDF VERSION:
avr-libc Reference Manual 20030417cvs
Generated by Doxygen 1.2.18 Tue Apr 22 09:54:05 2003

chapter 5.16.2.12 #define outp(val, sfr) outb(sfr, val)

Deprecated:
For backwards compatibility only. This macro will eventually be removed.

Use outb() in new programs.


As well as there are also same mention on html manual. I also can't find any 
outb() mention on deprecated function list. At least, I find this version of 
documentation with \WinAVR\doc\avr-libc\...

Thanks.

outb() [and inb()/outw()] are _not_ deprecated. Only outp() and inp() have been 
deprecated.

There are some portability issues that are better handled by using outb() 
instead of the <SFR> = <VAL>; idiom. Therefore, outb()/inb()/outw()/inw() will 
probably see a long life in avr-libc.

The avrfreaks posting was incorrect.

One caveat: Since the last stable release (20020203), the order of the 
arguments for outb()/outw() has changes.
