Oh. I think I figured out how to reproduce it reliably:
make -s clean
make -j pg_dumpall -C src/bin/pg_dump/
...
x86_64-w64-mingw32-gcc: error: win32ver.o: No such file or directory
The problem looks to be that pg_dumpall doesn't have a dependency on OBJs,
which in turn is what contains the dependency on WIN32RES, which in turn
contains win32ver.o. So the build succeeds if pg_dump/restores's dependencies
are built first, but not if pg_dumpall starts to be built before that...
Seems we just need to add $(WIN32RES) to pg_dumpall: ?
