GnuPG 1.3.4 SHA256 problem?

[Joe Vender]

I've compiled the gnupg 1.3.4 code which is on the download site using 
MinGW on windows and am using it on windows. When I set

  digest-algo SHA256

in my gpg.conf file, and then try to clearsign (or anything else), I get 
the following:

"DSA requires the use of 160 bit hash algorithm
clearsign failed: general error"

If I use SHA1 as the digest-algo, everything seems to work. I thought 
that this version was supposed to have SHA256 read and write ability. 
What am I doing wrong?
