Yes. But the solution then is to not unit test your library that way. You 
build it as a binary with an empty main and run that. It may be that compiling 
it as a library and then linking should work, but unless you want to have the 
unit test stuff compiled into your library normally (I wouldn't think so), 
you'll have to compile it separately for unit testing anyhow, so I don't think 
that it's really a big issue. You just have to realize that you need to not 
compile your library as a library when compiling your -unittest build.
