Hmm. The oldest gcc versions remaining in the buildfarm seem to be curculio | configure: using compiler=gcc (GCC) 4.2.1 20070719 frogfish | configure: using compiler=gcc (Debian 4.6.3-14) 4.6.3 lapwing | configure: using compiler=gcc (Debian 4.7.2-5) 4.7.2 skate | configure: using compiler=gcc-4.7 (Debian 4.7.2-5) 4.7.2 snapper | configure: using compiler=gcc-4.7 (Debian 4.7.2-5) 4.7.2 buri | configure: using compiler=gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-44) chub | configure: using compiler=gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-44) dhole | configure: using compiler=gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-44) mantid | configure: using compiler=gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-44) prion | configure: using compiler=gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-28) rhinoceros | configure: using compiler=gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-44) siskin | configure: using compiler=gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-44) shelduck | configure: using compiler=gcc (SUSE Linux) 4.8.5 topminnow | configure: using compiler=gcc (Debian 4.9.2-10+deb8u1) 4.9.2 so curculio should be the only one that's at risk here. Maybe just upgrading it is the right answer. regards, tom lane
