Enables and disables the generation of stack-overflow checking code.
Syntax:
{$S+} or {$S-}
Default:
{$S-}
Remarks:
If {$S+} defined, the compiler generates code at the beginning of each
procedure or function to check whether there is sufficient stack space
for the local variables and other temporary storage.
This option is not supported by
current version of compiler and will be ignored.
