From 4c1324589692e6cac7be294607ac3d8d9f46c2d2 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Wed, 4 Mar 2009 22:08:53 +0000 Subject: Put back our old workaround for machines that declare cbrt() in math.h but fail to provide the function itself. Not sure how we escaped testing anything later than 7.3 on such cases, but they still exist, as per André Volpato's report about AIX 5.3.
