Yes, you're right. If I had time, I'll do it. No wonder the strip -R
would save me some time :)

Yes, they do. AFAIK, nasm has an '-f bin' option and fasm has 'format
binary' directive, which could help their users generate binary files.

I often use this kind of feature of assemblers to produce executables
directly, not for _object_ files to be linked. IMHO, the problem of this
feature is how to generate plain binary for multi-section code. Nasm
simply concentrates its assembled sections, while fasm will report an
error of conflict between 'binary' and 'section' directives. Hmm..
considering this, gas has more flexibility.
