Default Behavior of the Compiler

If you do not specify any options when you invoke the Intel® C++ Compiler, the compiler performs the following:

• produces an executable file
• invokes options specified in a configuration file first
• searches for header files in known locations
• sets 16 bytes as the strictest alignment constraint for structures
• displays error and warning messages
• uses ANSI with extensions
• performs standard optimizations
• on operating systems that support characters in Unicode* (multi-byte) format, the compiler will process file names containing these characters
• if the compiler does not recognize a command-line option, that option is ignored and a warning is displayed
