NOTES-----I've checked out HPUX (well, version 11 at least) and shl_t isa pointer type so it's safe to use in the way it has been indso_dl.c. On the other hand, HPUX11 support dlfcn too andaccording to their man page, prefer developers to move to that.I'll leave Richard's changes there as I guess dso_dl is neededfor HPUX10.20.There is now a callback scheme in place where filename conversion can(a) be turned off altogether through the use of the    DSO_FLAG_NO_NAME_TRANSLATION flag,(b) be handled by default using the default DSO_METHOD's converter(c) overriden per-DSO by setting the override callback(d) a mix of (b) and (c) - eg. implement an override callback that;    (i) checks if we're win32 (if(strstr(dso->meth->name, "win32")....)        and if so, convert "blah" into "blah32.dll" (the default is	otherwise to make it "blah.dll").    (ii) default to the normal behaviour - we're not on win32, eg.         finish with (return dso->meth->dso_name_converter(dso,NULL)).
