Yes.  Case in point is the very -fPIC we are discussing.  If the configure
tests -fPIC and due to a warning decides it can't be used, it doesn't
simply abort, but continues the process thru the rest of the config and
into the compile and linking.  Only later in the linking, and gets an error
similar to that of this thread because shared objects require -fPIC on
this platform, does it realize things went wrong.  Then the error it spits
out says to compile with -fPIC, when that's what it would have been doing
if the config hadn't misinterpreted an unrelated warning on the -fPIC test
as an indication that it shouldn't be used.

(The other half of your post addressed in the other subthread.)
