Fixed bug 1390 - X11_KeyToUnicode

manuel.montezelo 2012-01-22 08:56:18 PST

We had the following bug report at Debian:
http://bugs.debian.org/376560

Same one in Ubuntu:
https://bugs.launchpad.net/ubuntu/+source/libsdl1.2/+bug/66217

We've been including a patch since then (attached) to actually export the
symbol, since 2006.  In the last release the function seems to be there, alive
and kicking.

It's affecting other people too:
