MATLAB: Help with ‘Make Error’ in Simulink

make errorsimulinkstateflow

I am running a simulation in Simulink and get the following error. I am compiling with Windows SDK (current version). I tried to delete the slprj folder it generates but it still throws this. I've also tried switching to the visual c++ 2010 express and I get a similar error.
I would appreciate any help.

Looks like Stateflow (or an Embedded MATLAB Function block) is generating C code that strains against Visual Studio's limitation for number of levels of nested parentheses. Please report this to MathWorks Tech Support - they might be able to suggest a workaround and file a bug report if this is indeed a bug.
