Problem with ModelSim and Xilinx PCIe endpoint block plus simulation

I'm trying to run through simulation of the PIO example given with
Xilinx PCIe endpoint block plus. However, when I run modelsim with
the .do file given in the example, I get:

vmap work {C:/Documents and Settings/PoojanW/My Documents/PCIeEPBP/
pciex4/simulation/functional/work}
# Copying c:\modeltech_pe_6.5\win32pe/../modelsim.ini to modelsim.ini
# Modifying modelsim.ini
# ** Warning: Copied c:\modeltech_pe_6.5\win32pe/../modelsim.ini to
modelsim.ini.
#          Updated modelsim.ini.
vlib work
# ** Warning: (vlib-34) Library already exists at "work".
vmap work
# Reading modelsim.ini
# "work" maps to directory C:/Documents and Settings/PoojanW/My
Documents/PCIeEPBP/pciex4/simulation/functional/work.
vcom -work work -f board_rtl.f
# Model Technology ModelSim PE vcom 6.5 Compiler 2009.01 Jan 22 2009
# -- Loading package standard
# ** Error: ../../example_design/xilinx_pci_exp_ep.v(1): near "/":
syntax error
# ** Error: ../../../pciex4.v(1): VHDL Compiler exiting
# c:/modeltech_pe_6.5/win32pe/vcom failed.

(For illustration, I executed the .do file manually line by line).

I don't know much about ModelSim (thus the post), but it seems like it
thinks  ../../example_design/xilinx_pci_exp_ep.v is a VHDL file
(rather than Verilog). How do I fix this misunderstanding?

You could try right-clicking on the project, selecting Properties, and
setting the preferred language to Verilog? I don't know if this will
help, but it's worth a try,

The problem is apparently in the example script. vcom is the VHDL compiler,
which IMO can legitimately assume its input is VHDL...

I think you need to edit the script (or find a more suitable one) to use the
Verilog compiler. I think it's called vlog, but I've never used it.
