I've been having some problems running the regression tests using
meson on Windows. This seems to be down to initdb being compiled with
a version of pg_config_paths.h left over from the msvc build which had
been used on that source tree previously.
Generally when there are files left over the meson build script will
detect this and ask you to run make maintainer-clean. That's useful
on Linux, but on Windows you're just left to manually remove the
conflicting files which are listed. Unfortunately, pg_config_paths.h
wasn't listed, which I think was missed because it's not generated
during configure, but during the actual make build. (see
src/port/Makefile)
Linux users are unlikely to experience this issue as they're likely
just going to run make maintainer-clean as instructed by the meson
error message.
The attached patch adds pg_config_paths.h to the generated_sources_ac
variable so that if that file exists, meson will provide an error
message to mention this. i.e:
> meson.build:2953:2: ERROR: Problem encountered:
> ****
> Non-clean source code directory detected.
> To build with meson the source tree may not have an in-place, ./configure

Are there any objections to the attached being applied?
