I don't know where do you think it can be configured, binutils? because I'm talking
about the current situation:

1) The start of the section is aligned by djgpp.djl
2) The aligment of the functions can be controled by -malign-functions
3) binutils controls the aligment between .o files (8 currently).

I think you are talking about (3) and not (2). Is that correct?
