[PATCH 8/8] setools -- Preserve ABI between GCC 4.3 and GCC 4.4

[Laurent Bigonville <bigon@xxxxxxxxxx>]

Hi,

I'm really not sure about that one.

It seems that the ABI has changed between 4.3 and GCC 4.4, this patch
is creating a compatibility alias for libsefs functions.

Cheers,
Laurent Bigonville

Description: libsefs built with GCC 4.3 is not binary-compatible with itself built with GCC 4.4
 That's because mangling of va_list has changed in GCC 4.4.
 To cope with this situation, provide compatibility aliases for the affected symbols
 and update symbol files accordingly.
