No subject

a developers perspective it's only half of an answer. It explains why
linking NVWISH2.2 failed; however, it doesn't explain why linking the
configure test succeeded.

The whole point of the configure test is to determine whether a
particular set of switches will result in successfully constructing a
program which requires a particular function. A false positive is the
worst possible result, because configure claims that everything is OK,
then goes on to add switches will break the build process.
