In the immediate, I think your best course of action would be to see
if you can just override these tests. It seems unlikely to me that you
would really need conversion from these legacy codepages for normal
usage of samba. (BTW I'm surprised nobody else has reported this
before... does anybody else know why it hasn't come up..?)

Adding cp850 and other DOS codepages should not be hard and should not
take up much additional size in iconv, but it's also nontrivial to do
without my tools to generate the tables, which are not published.
Publishing them is something I should really get around to doing,
since their absence affects the ability of others to modify the code
in meaningful ways; I need to apologize for not doing so already.
