Somewhere I had got it in my head that global variables had static storage
class by default. I guess I was wrong.

Technically yes; the original K&R C book had the one-definition rule in it.
 Early C compilers did not work this way, however, and by the time that book
was published (1978) there was already a large body of code that assumed the
"common" model (also Ritchie's preference, I believe).  In practice most
compilers still default to this model because a lot of widely used stuff
will break if they don't, and the behavior is given in J.5.11 of C99 as a
common extension.

Use -fno-common to turn it off.
