* How do we solve the problem that a program linked against a static
libc doesn't have dynamic access to the whole library symbol table?

* tests/reload fails on linuxoldld:
dld_link: multiple definitions of symbol: 
dld_get_func: multiple definitions of symbol: 

* dld_function_executable_p gives false negatives: i.e. it reports
that a function is not executable when it really is.

* dld_init can fail completely if our parent process gives us a
nonstandard argv[0] when it calls exec(2).  This is bad.  See TODO for
a possible solution on systems with shared libraries (i.e. write our
own ld.so).

* C++ support was never well-integrated with the rest of dld.  It has
been temporarily removed from the library, until it may be properly
written.

* On VAX Ultrix 4.4, dld aborts with DLD_EBADRELOC when it encounters
absolute symbols (N_ABS).  What *are* absolute symbols?
