The problem here is simply that the postgres.imp target has no dependency in

the Makefile.aix and thus gmake thinks it can start with this step.

This is now the default. The c++ check using gcc is busted, since the
test code is C only and is compiled with gcc. gcc does not switch to C++

Don't rely on gunzip, use gzip -cd instead.
