You are very lucky that your compiler compiled you first program, because it
is not usual to be able to auto-initialise arrays. I think your compiler has
a way around with the first program, however the second program would use a
more complex  initialisationroutine. I think that's way it fails to compile.

It is, however, no problem if you make the declarations global or static.
But then they are initialised only once, not each time the function is entered.
