I looked up Make Errors here, and most of the issues were solved by calling 'mex -setup'. I gave that a shot, and everything looked fine. I'm using MATLAB R2011a Student Version along with its built-in lcc C Compiler.
My Simulink model consists of two MATLAB functions, some constants and 'From Workspace' sources. One of the MATLAB functions is 154 lines long and includes four extrinsic functions, all of which are declared as such at the beginning of the function. The other is basically a placeholder and passes the outputs as the same as inputs.
Here are the errors, buried in a long error report:
