config.log file as requested

(In [1798]) OpenBSD has an old version of GCC which doesn't know about a lot of -W flags Also, OpenBSD has some strange header prerequisites, which I had to handle. Anyways, the code now configures & compiles under OpenBSD 4.0, which hopefully means 3.9 too. If not, too bad, someone else will have to figure it out. fixes #146

[aturner]

(In [1800]) whoops, didn't mean for this to get deleted. fixes #146

[aturner]

(In [1808]) fix -Wfatal-errors fixes #146
