The "some reason" is so that you can write assembler code that can call 
any C function. Without the leading _, any C function that has the same 
spelling as a macro assembler pseudo-op or register will fail to assemble.

Linux avoided that problem by having a really ugly asm syntax that won't 
conflict with C names. Linux assembler format really sucks all the joy 
out of writing in assembler.
