X-Git-Tag: REL_18_1~85
X-Git-Url: http://git.postgresql.org/gitweb/static/gitweb.js?a=commitdiff_plain;h=15d7dded0e930b5781b2c0e591c1b45eb078a248;p=postgresql.git

Commit c8af5019be added a forward declaration for this typedef that
caused redefinitions, which are not valid in C99.

Per buildfarm members longfin and sifaka.
