are there equivalent flags on Studio C Compiler for -Wall and -fno-strict-aliasing. How should I modify Makefile to avoid warnigs or errors related to this gcc flags?
You could just remove them...
-Wall is for warnings, and here warnings come mostly when you use lint instead of cc (and cc warnings come by default)
-fno-strict-aliasing would be -xalias_level=any, which is the default
