Can't compile GSM from source

[Ratintosh]

Whenever I run "make", I get loads of invalid operand errors and I honestly have no idea why. I can build other PS2 apps just fine but this one seems different. I've got PS2SDK installed and everything. Below is the errors I keep getting when trying to make the project.

$ make

Honestly any help would be really appreciated.
