I guess that's ok, if you are using DWARF2.  But we're not.

On the other hand (thinking out loud), if DWARF2 is not a 
requirement, I suppose gdb could be hacked to allow a new path 
command of headers (much like dir), and have gdb expression 
processing handle undefined function id references to see if they are 
defined as macros in the specified headers, expand it, and use the 
result.  I am not sure how hard that would be to do and it does have 
the down side of not being able to handle conditionally defined 
macros.
