libmudflap is a gcc library used for the mudflap pointer
|
|
debugging functionality. It is only needed if you intend to
|
|
use the -fmudflap gcc flag.
|
|
|
|
See http://gcc.gnu.org/wiki/Mudflap_Pointer_Debugging and
|
|
the help of the gcc -fmudflap option for more details.
|
|
|
|
If you're unsure, leave this option disabled.
