Hi,

Compiling the latest alsa-driver with kernel > 2.6.31 results in gcd() symbol duplication. Although there's a check in configure for linux/gcd.h, no boolean is adjusted according to that.

In acore/wrappers.c, gcd() is exported if CONFIG_GCD is not defined which seems always the case for now.

Something like the following fixes the problem for me:

Thanks!
