Subject: Rename our substitute qsort to pg_qsort at the link-symbol level (but
X-Git-Tag: REL8_2_BETA2~27
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=4887f5f979f36a5d389e898edca61bd6aa4f0f20;p=postgresql

Rename our substitute qsort to pg_qsort at the link-symbol level (but
provide a macro so code can still just say qsort).  Avoids linker warnings
on pickier platforms such as Darwin, and outright failure on MSVC.
