Verilog porting woes

I'm a VHDL guy trying to port some verilog to a cyclone3.

The unmodified verilog source produces parse type errors when quartus attempts to compile it.

The thing that has me confused is that company X's software compiles this without problem. I'm thinking that there must be some language feature that is throwing quartus off. Not being a Verilog expert I'm a little unsure of how to proceed.

I've also tried all three settings for Verilog version in the analysis and synthesis settings.

Does anyone have ideas of how to get this to compile?

Thanks,

Here is the source file "sha256_pipes2.v":
