Any GCC experts out there?

I can verify that at least on Linux, what Eriks writes is true.
However, according to "man ld", the situation may be different on Solaris:

  "By default, on SunOS, the linker will form a runtime search patch out of 
all the -L options it is given."

Which I interpret as Russel did - assuming gcc uses GNU ld.

You can try the "-rpath" option to ld (gcc doesn't appear to accept this) if 
you're dead set on *not* changing your LD_LIBRARY_PATH/ld.so.conf/whatever.

Cut-and-pasted from "man ld":
  -rpath dir
             Add  a  directory  to the runtime library search path. ...

(Using rpath is generally considered bad practice though - google "rpath 
considered harmful")
