Description:
According to C and C++ standards, symbols starting with underscore
are reserved and should not be used from users source. Normally
this doesn't matter, but as can be seen from the attached text file
the system libraries or compiler might add its own symbols that
starts with underscore that risk clashing with the MySQL source
ones.

As seen in Bug#35743 some linkers even try protect the symbols
that start with underscore forcing the use of special flags to make
them visible to plugins, in this case for AIX and i5/OS.

How to repeat:
See Bug#35743

Suggested fix:
Stop prefixing symbols with underscore in the MySQL source, and replace
the current prefixes with something that doesn't start with an underscore.
