Here is my attempt to compile and run the

I would advise switching to the current ghdl-0.31-mcode-win32 build
from SourceForge.
Download Page:
http://sourceforge.net/projects/ghdl-updates/files/Builds/ghdl-0.31/Windows/
Windows Install Wiki Page:
http://sourceforge.net/p/ghdl-updates/wiki/Windows%20ghdl-0.31%20install%20from%20zip/
I can successfully run the DLX example with the following using
ghdl-0.31-mcode-win32:
ghdl -i --workdir=work *.vhdl
ghdl -m --workdir=work dlx_test_behaviour
ghdl -e --workdir=work dlx_test_behaviour
ghdl -r --workdir=work dlx_test_behaviour --assert-level=note
I tend to include the elaborate stage, which although not strictly
necessary for the mcode build, more closely resembles GHDL usage for
the gcc back end.
============
Using GHDL with obsolete synposys std_logic_arith, std_logic_{un}signed
libraries:
Add the --ieee=synopsys option to the commands lines.
============
Using GHDL with GTKWave
Adding the --wave option to the run command line will generate a .ghw
file that can be viewed with GTKWave.
Note that this waveform capture will slow the simulation.
ghdl -r --workdir=work.ghd testbench --stop-time=500ms
--wave=ghdl_sim.ghw
If the testbench stops the clock upon completion, there is no need for
the --stop-time option.
============
Some other windows GHDL scripting examples in can be found in my
perpetually unfinished homebrew processor project:
Switch debouncer stimulus testbench:
https://code.google.com/p/yard-1/source/browse/trunk/hdl/common/debounce/test/
UART test bench:
https://code.google.com/p/yard-1/source/browse/trunk/hdl/cores/m_uart/test/
I typically use batch file(s) that look like this:
ghdl -a -v --workdir=work.ghd ..\m_uart_pkg.vhd
..\simple_baud_gen.vhd ..\m_uart.vhd m_uart_tb.vhd
ghdl -e --workdir=work.ghd testbench
ghdl -r --workdir=work.ghd testbench --wave=ghdl_sim.ghw
