matlab compiler on osx: mclSetExitCode declaration not found in Matlab R2011b

Dear all, I'm trying to compile a simple example on osx 10.8, which used to work with r2010. But seems that the function mcSetExitCode is not declared. I thought I was missing some header files, but doing a grep of mcSetExitCode inside matlabs directory gave no results. Has anyone experienced a similar behaviour?

EDIT: Seems that the examples found in /Applications/MATLAB_R2011b.app/extern/examples/compiler/matrixdriver.cpp does not use this anymore. Was it obsoleted?

Thanks in advance. Regards, Juan
