These files used to be stubs which used #ifdef PIC to decide whether to
use the real dlopen() version or the stub version from the src/contrib/tcl
sources. Now, with the our stubs gone, the .PATH directive causes them to
be compiled directly from src/contrib/tcl/{unix,generic}. You might need
to rebuild your depend rules though as they may have stale paths.
Also, this is a generated file. This should not have been edited here.
