Tried it. It didn't appear to work, although it may have been something
silly I did. Basically, I did a:
setenv("LD_LIBRARY_PATH",".",1);
I was hoping to get the loader to use the current directory to find
libraries, so a later call to:
dlopen("foo.so",RTLD_NOW | RTLD_GLOBAL);
would find foo.so in the current directory.
