Any reason for this code not to work

[Adrian McMenamin]

As referred to in an earlier post I am having a lot of problems with
compiling the ALSA control/mixer code on my Dreamcast using
uclibc/buildroot.

>From what I can gather the problem seems to be lines such as this one in
the alsa headers:


#define snd_kcontrol(n) list_entry(n, snd_kcontrol_t, list)

Is there any reason why this sort of code should (silently) be failed by
the CPP that buildroot builds?
