I must have missed this one.  Where is "the usual linker magic" described 
in POSIX/UNIX?

If you mean "versioning" the library or the function, then you are actually 
saying that we will impose a new ABI on those implementations that have to 
move the structure elements around in order to conform.

"Common existing practice" has to be "defined" from a broader selection of 
implementations than just Solaris and GNU.
