When compiling, the ANIM directive is passed to the compiler to produce .int, .gnt or .o code that can be used by the Animator.
When linking, the linker creates additional information needed for the use of a symbolic debugger such as dbx. With this flag set, no symbols are stripped from the output file. This flag is passed through to the C or C++ compiler if any .c or .C files respectively are being processed, so it is useful if your program contains some C or C++ functions that you want to debug.
