DESCRIPTION
When _FORTIFY_SOURCE bounds checking is enabled as described below, the above functions get overwritten to use the __builtin_object_size(3)
function to compute the size of str, if known at compile time, and perform bounds check on it in order to avoid data buffer or stack buffer
overflows. If an overflow is detected, the routines will call abort(3).
To enable these function overrides the following should be added to the gcc(1) command line: ``-I/usr/include/ssp'' to override the standard
include files and ``-D_FORTIFY_SOURCE=1'' or ``-D_FORTIFY_SOURCE=2''.
If _FORTIFY_SOURCE is set to 1 the code will compute the maximum possible buffer size for str, and if set to 2 it will compute the minimum
buffer size.
