 To fix the implicit declaration of `exit`, please apply the patch attached
 to this bug report:

 https://savannah.gnu.org/bugs/index.php?63679

 The implicit declaration of `strchr` is intentional and should be
 suppressed according to WimplicitFunctionDeclaration#strchr by adding:

 {{{
 # https://trac.macports.org/wiki/WimplicitFunctionDeclaration#strchr
 configure.checks.implicit_function_declaration.whitelist-append strchr
 }}}
