Yeah, but if the Makefile says "CC = ccache gcc" then anybody
trying to build under PGXS will fail if they don't have ccache
installed. So I think Greg has a point.
On typical Red Hat setups, it's not necessary to mention ccache
explicitly to use it; instead that's managed via PATH. For
example, I have
$ which gcc
/usr/lib64/ccache/gcc
$ ls -l /usr/lib64/ccache/gcc
lrwxrwxrwx. 1 root root 16 May 21 09:35 /usr/lib64/ccache/gcc -> ../../bin/ccache
so it Just Works. I'd suggest arranging the rpm builds to be
done similarly, and then you get ccache usage in the rpm build,
while the distributed Makefile will just say "CC = gcc" so
it will work for users whether they use ccache or not.
