SDL on cygwin as a whole must be fixed ;)
I'll see what's their take on the subject once i get a functionnal 
binary etc.

I see. It's much more reasonable. Tho i find rather strange that gcc 
doesn't put those in a special section and implicitely asks for a 16 
bytes alignement for all constants (when it's only really needed for 
some specific target optimizations), but that's just my armchair expert 
opinion.
If the burden falls onto binutils, so be it.
Is that considered as a cygwin only 'issue' or a more general one, and 
where should i forward this discussion?
(it sounds like it's time to give PE & binutils a glance)

Thanks for your time,
	tbp.
