It doesn't really know about either, it doesn't look at spec files at
all.
Libtool does nothing more than link with $CC when it is know to work,
or else $LD if it proves to be necessary. The one wrinkle in this
formula is that when CC=gcc, libtool will try a dummy link to
determine whether `-lc' is implicitly added when the link phase is
handled by gcc.
It seems as though libtool needs to do more. Unfortunately my
knowledge of linkers and loaders is superficial, so you will need to
explain what it is that libtool is (or isn't) doing, and what you
would have expected libtool to do (or not do) in painstaking detail in
order for me to get a good grasp of what I can do to fix it :-(
Cheers,
Gary.
