Flexible variable declaration ?

[Chang jaehwa]

Hello?
When I compile in c-mode, the variable "compile-command" is set "make -k".
I want to change this variable to contain the name of current buffer.
For example, if I edit hello.c and command "M-x compile" , I want to assign
variable "compile-command" as "gcc -o hello hello.c" automatically.
How can I set variable to contain buffername in it?
