Thread: pgsql: Preserve intermediate .c files in coverage mode

Preserve intermediate .c files in coverage mode

The introduction of the .y -> .c pattern rule causes some .c files such
as bootparse.c to be considered intermediate files in the .y -> .c -> .o
rule chain, which make would automatically delete.  But in coverage
mode, the processing tools such as genhtml need those files, so mark
them as "precious" so that make preserves them.

[ blink... ]  I'd vote for making them precious all the time.  No such
behavioral change was discussed or agreed to, and I'm concerned about
possible side effects, for instance losing files that you don't have the
tools to rebuild when working from a distributed tarball.
