[MPlayer-cvslog] r35466 - in trunk: binary.ver configure

[reimar]

Author: reimar

New Revision: 35466

Log:
Add a version script to hide all symbols.

This should give better startup performance at least
and reduces the stripped binary size by about 500 kB for me.
However it means that stripped binaries will give only
completely useless backtraces since the compiler
will no be able to find the name of even a single function.

Added:
   trunk/binary.ver
Modified:
   trunk/configure
