That looks scary, can you please comment out this:
#define SHA1DC_ALLOW_UNALIGNED_ACCESS
In sha1dc/sha1.c and see if that helps, alternatively comment out the
ifdefs guarded by "#ifdef _MSC_VER" calls in sha1dc/sha1.c
The functional differences between 2.13.0 and 2.13.1 on that platform
should be none aside from possibly those changes, unless I've missed
something.
