parse error before `size_t' (audiofile)

["Brian J. Stults" <bs7452 csc albany edu>]

I'm getting a lot of messages like this while trying to install
audiofile from source.  Here's some of the output from configure:

In file included from /usr/local/include/stdio.h:57,
                 from audiofile.c:33:

There's a lot more, but I thought I'd just include a sample.  Does
anyone have some advice?

Thanks!
