Unfortunately, these switches tend to vary between compiler releases 
so it would be very difficult for libtool to know the valid switches 
for the compiler you are using.  If a package has been released for 
several years, the compiler options its libtool chooses to use may not 
work at all with the current version of the compiler.  That is why it 
is best for the end-user to take care of part of the heavy-lifting.
