This package contains GCC shared support library which is needed
for mudflap support.

For front-ends that support it (C and C++), instrument all risky
pointer/array dereferencing operations, some standard library
string/heap functions, and some other associated constructs with
range/validity tests. Modules so instrumented should be immune to
buffer overflows, invalid heap use, and some other classes of C/C++
programming errors.

Refer to the documentation for -fmudflap and -fmudflapth.
