: This program *should* print 0.900000, and with most compilers, it does.

Maybe I'm missing the point here... but it seems to me that the program
*should* print 0.8 -- since the "d" defined outside the block is initialized
to 0.8.  I don't have any books with me, but is "extern" *required* to
scope outside of the function? (I thought it just had to scope outside
the current block).
