It already does -- sort of.  The ILE compilers automatically know
where to find built-in functions and CEE functions.  They also know
where to find their own runtime support functions.  The CEE functions
are found using binding directories QILE and QLECWI.  The runtime
support for RPG is found using binding directory QRNXLE.  I suspect
you could add your own service programs and modules to QRNXLE or even
add all the QC2LE service programs.

But I do have to tell the compiler where to find MY libraries (unless
I stick them in /lib too).  However, I think the suggestion has merit
and support for all compilers to automatically use a QUSRBD binding
directory would be a helpful thing.

Nested BNDDIRs would be useful too if we can avoid recursive
references.

However from RPG IV's perspective it is not difficult -- just code an
H-spec with the appropriate BNDDIR keyword.  COBOL is missing BNDDIR
on the PROCESS statement.  C is missing BNDDIR as a #pragma.
