pg_regress: Use target-specific variable instead of overriding make rule

petere · petere · commit d66b31c94faf · 2012-02-07T22:42:19.000+02:00
Use a target-specific variable to add to CPPFLAGS instead of writing a
custom .c -&gt; .o rule.  This will ensure that dependency tracking is
used when enabled.
