I think it's to libassuan, right?

I am currently (back) porting gnupg/agent/command-ssh.c thing to
libassuan, which touches same files.

Please describe your problem.  For me, it is just moving the check (I
compared the resulted configure scripts (with your change, original)).

I wonder the reason why original version breaked on Cygwin and how.

I'd just moving the check unconditional (like one in gnupg), since
we also need to check sys/ucred.h.
