Your patch is applied to git master.

To answer your question, my intent was to handle many of the
standard libraries internally. You noticed this in the code that
you patched. Types and other declarations can be efficiently
compiled into the compiler itself. For many of the more basic
types, this is the only reasonable way to do it and I suspect
that most VHDL compilers work the same way.

For many standard functions, there are straight forward translations
to Verilog analogs, so the Icarus Verilog runtime is leveraged,
and for others, it is easy enough to make the compiler generate
references to system tasks to implement the library functions.

So that is where we are heading with the standard libraries.
