Not the most basic (see example below...)

You technically _don't_ need the #include, BUT, it's VERY good programming
practice.  Helps to avoid calling convention problems (for ANSI and later)
plus, gives you access to #defines (like NULL for example!), structs,
typdefs, extern variables, etc.  Anyone who want's to do a good job of C
coding will include the appropriate header files to be safe.  The only
thing you gain by omitting them is compile time.

Now, the most simple C program is:

main(){write(1,"hello, world!\n",14);}

This requires the least amount of linking and produces the same result.  Of
course, one has to count the number of characters in the string, but at
least you save the computer from having to do such an arduous task. :-)
