Hi all,
I'm trying to build alsa from source. I'm guessing (I was not able to find any instructions on how to build alsa) that I build alsa-lib first. I'm compiling it with gcc 4.2.1. However, when I build it, I get the following errors:

(I know it's a lot of text, but I'm not sure how much is needed to determine what's wrong, not being overly familiar with alsa myself.)
Can someone help me out please? Remember that since I'm using cygwin, it could be as simple as not having all the packages installed.
Thanks, Nathan
