Hello,
i try to get my compiler with execute mex -setup, but it results
Would you like mex to locate installed compilers [y]/n? y
Select a compiler:
[1] Lcc-win32 C 2.4.1 in D:\PROGRA~2\MATLAB~2\sys\lcc
[0] None
Compiler: 1
Please verify your choices:
Compiler: Lcc-win32 C 2.4.1
Location: D:\PROGRA~2\MATLAB~2\sys\lcc
Are these correct [y]/n? y
Trying to update options file: C:\Documents and Settings\user\Application Data\MathWorks\MATLAB\R2011a\mexopts.bat
From template: D:\PROGRA~2\MATLAB~2\bin\win32\mexopts\lccopts.bat
Done . . .

You get an error, when you try to compile svm.cpp, because this is a C++ file, while the LCC compiler is a C-Compiler.
To compile C++ files, a C++ compiler is required. See http://www.mathworks.com/support/compilers/R2011a/win32.html for a list of supported compilers. I can recommend the Microsoft Visual C++ 2010 Express compiler. For the 2011b/64 bit and 2009a/32 versions I could compile succesfully after installing the SDKs only, but I did not test this for 2011a/32.

You do not need to do anything more. The warning is a reminder that some old routines will soon not be supported; it is something you do not need to be concerned with unless you plan to compile old routines.

So, if everything is ok, why i get an error when i try to execute make.m in libsvm? D:\PROGRA~2\MATLAB~2\BIN\MEX.PL: Error: Compile of '..\svm.cpp' failed.

tedy: Perhaps you have syntax errors in your MEX-file? It will help if you post the full error (you may want to compile with the mex -v option for verbose mode).
