And it sounds like a bug to the GNU Configure script (at least, the version that comes with ftp://download.sourceforge.net/pub/mirrors/OpenBSD/OpenSSH/portable/openssh- 2.1.1p4.tar.gz). That script reproduces the problem with this little C program: #include int main(void) { char b[5]; snprintf(b,5,"123456789"); return(b[4]!='\0'); } The correct return value is 0, but on Cygwin, we get non-zero. This problem prevents me from building openssh.
