Why do I receive a make error in Stateflow when I have a # character in my directory name?

When I am in a directory with a pound sign, for example #mydir or ##mydir, I receive a make error when I try to simulate my Stateflow model.

 lcc preprocessor fatal: Can't open input file -c 

 "d:\matlab6p5p1\sys\lcc\bin\lcc.exe" -c -Zp8 -DMATLAB_MEX_FILE -noregistrylookup -I"d:\matlab6p5p1\sys\lcc\include"  -I"d:\matlab6p5p1\extern\include"  -I"d:\matlab6p5p1\simulink\include"  -I"d:\matlab6p5p1\stateflow\c\mex\include"  -I"d:\matlab6p5p1\stateflow\c\debugger\include"  

 -I"g:\1427087\giac# "giac_sfun.c" 

 d:\matlab6p5p1\sys\lcc\bin\lccmake: Error code 1

This enhancement has been incorporated in Release 2012b (R2012b).

For previous product releases: All make utilities treat # as a comment character and this leads to generated code failing to compile.

The only workaround is to not to use the # character in the directory name.
