Disabling reading of charsets files?

Hi,

I see that mysql client library reads the charsets/Index.xml file from the
installation directory every time that clent initializes itself. The path
to that file is hardwired into the library and cannot be changed currently
(as of version 5.0.18 that we use). This could become a limiting factor
in some cases:

- one cannot move the installation directory to a different place without
rebuilding libraries
- in our particular case when we have central installation and _many_
clients it can also be a performance hit

So we are looking for a way to either disable or run-time configure the
reading of the charsets files. There are possible options how we could do
that, I think our preferences would be (in this order):

1. compile-time option to completely disable external charsets and use
only built-in charsets
2. run-time option to disable external charsets
3. run-time option to specify different location of charsets directory

Does anybody know how difficult would it be to convince mysql developers
to implement something like this?

Andy.
