Uninitialized externals and statics.

[Dror Matalon]

	K&R 2.4 say "External and static variables are initialized 
to zero by default, but it is good style to state the initialization
anyway."

	Is this really portable ? I always initialize globals but I want
to know if I need to change some old stuff that counts on uninitialized
variables being initialized to zero.
