From 3addc94aff0b10730c6b023e1a4a5d677e53d5a7 Mon Sep 17 00:00:00 2001

Subject: Replace instances of export VAR=VAL with VAR=VAL; export VAR

It might be POSIX, but there are shells that do not like the
expression 'export VAR=VAL'.  To be on the safe side, rewrite them
into 'VAR=VAL' and 'export VAR'.
