Ok, I've removed the inline from the header.

In the process I found a place in dwarf2out that was using dbx 
register numbers instead of dwarf2 register numbers.  Tsk Tsk.
Of course, on most targets they're the same thing.  But still...

Tested on x86_64-linux, arm-eabi (arm-sim).
Cross-compiled ia64-linux, mips-sgi-irix6.5.
