Default

Standard libraries are used during compilation. |
Description
This option ensures that compilation takes place in a freestanding environment. The compiler assumes that the standard library may not exist and program startup may not necessarily be at main. This environment meets the definition of a freestanding environment as described in the C and C++ standard.
An example of an application requiring such an environment is an OS kernel.
Note
When you specify this option, the compiler will not assume the presence of compiler-specific libraries. It will only generate calls that appear in the source code.
