Errors building mozilla thunderbird 38.7.0 with gcc 6


I could be wrong but it appears there are 2 distinct errors - in gcc6 itself (specifically in header files) and in thunderbird (although this version does compile with gcc 4.8.2)

Background - rebuilding the thunderbird 38.7.0 rpm (from redhat) using gcc6 and binutild 2.26 in RHEL 6.7

I'm wandering if this is a result of moving to std-14 as default and thus not a bug, or if there is some issue with stdlib.h/cstdlib ?
