-std puts the compiler into relaxed-ANSI mode, instead of the default, which
is K&R. This flag was actually added by autoconf itself---the build failure I
quoted was obtained with all *FLAGS variables unset.
(The only other options here are -std1 [strict ANSI], and -ms [Microsoft
Visual C compatible])
