DSAUSER compiler option

Starting from z/OS® V1R13 XL C++ compiler, the DSAUSER option is supported. When the METAL option is in effect, the DSAUSER option requests a user field of the size of a pointer to be reserved on the stack. The default is NODSAUSER. For more information, see DSAUSER | NODSAUSER (C only) that is documented in z/OS XL C/C++ User's Guide.
