If you restrict yourself to c89 that would match the requirement.  The 
actual requirement is rather: "needs to be compilable with an old msvc". 
I don't know which exact version of msvc that is, but it's one that 
doesn't support designated initializers and some other c99 stuff. 
grischka uses such msvc.

No particular reason most probably (except in the case when specifically 
the standard mandated behaviour of 'int main()' is tested).  If you prefer 
the void form for new tests use it.  (please don't change existing tests 
except for good reasons)


Ciao,
