I believe the meaning of "extern" in combination with other
storage-class specifiers was picked to work with existing old code
from before "extern" was added to the language. 

 
Assuming you mean the "C" language I don't quite understand the last
part of the sentence. Wasn't 'extern' already in "K&R" - so what was
"the language" before the addition of 'extern'?
 
Or did you just mean to say "[...] before _combinations_ of 'extern'

K&R was published in 1978, 5 years after C got its first users.
Back in 1973-74 C language was significantly different from what it
became few years later.

The earliest C reference I have is cman74.pdf, currently at
<http://cm.bell-labs.co/who/dmr/cman74.pdf>.  It includes "extern" in
the list of keywords.

It was inherited from B, which had "extrn" as a keyword as of 1972.
