Doc Text:
MPX feature in GCC requires Red Hat Developer Toolset version of the libmpx library The libmpxwrappers library is missing in the gcc-libraries version of the libmpx library. As a consequence, the Memory Protection Extensions (MPX) feature might not work correctly in GCC, and the application might not link properly. To work around this problem, use the Red Hat Developer Toolset 4.0 version of the libmpx library.
