"The difficult we do immediately, the impossible takes longer!" :)

Substituting "-soname=" with "+h " is simple (for hpux once).
And it's easier to ignore "-soname=*" for aix.

Unlikely, but who can say ?

Who knows what things we do have/want/need ?

These are done right now:

*) have prefix in default library search path
*) have prefix in default runpath
*) darwin: pass "-search_paths_first"
   (since brandnew version 0.svn72 ;-) )
*) aix: default to "-brtl" to have real shared-libs by default
*) aix: pass runpath as one arg: "-blibpath:path1:path2:pathN"
*) interix: pass runpath as two args: "-rpath" "path1:path2:pathN"
*) aix/interix: uniq and resort runpath to "others:prefix:system"
