Avoid implicit declaration of exit. This requires a C language
feature that was removed in 1999. Future compilers are likely to
reject implicit function declarations by default.
No need to upstream this because it is part of autoconf, not this
package. Re-running autoconf makes the issue go away (after
porting configure.in).
