after running a simple ./configure --prefix=/usr/local/mysql and then
running gmake I get this error:

it's complaining about this line:

if (select((int) max_used_connection,&readFDs,0,0,0) < 0)

I'm asking here because I've never had this problem before I tried the
newest snapshot.  Thanks for any help.
