Errors are certainly printed.  What is not printed are the steps that
libtool is taking to perform the requested commands. The result is 1/4
to 1/3 the output while building.

If libtool should happen to fail (gasp!) then it is useful for it to
print everything it is doing.  Luckily libtool rarely fails these days
so verbose output is perhaps best left for people developing/debugging

If you *really* want to know what is going on, then I suggest that you
always add -vH to CPPFLAGS and CFLAGS so that the compiler can tell
you exactly what it is doing. :-)
