That was one of the first things I tried after verifying the fix.
It seems to want to pull the object code from somewhere else.  My
guess is the libgnat.a file.  I even tried compiling with -a to
force it to recompile the runtime libraries, but it only generated
a bunch of .o files and no libgnat.a file (in my project's local
object file directory).  That said, keeping the .o file in my
local directory seemed to work to override the RTS version.  I was
just hoping to make the change more permanent.
