Ah, I might have inadequate operation just before the branch switching.

$ cd ~/source/pgsql     <-- REL9_5_STABLE; already built
$ git checkout master
$ cp -r ~/source/pgsql ~/repo/pgsql-kg
$ cd ~/repo/pgsql-kg
$ ./configure
$ make clean
$ make                  <-- repl_gram.c raised an error

~/source/pgsql is a copy of community's branch; with no my own modification.
To keep it clean, I copied entire repository to other directory, but cp command
updated the file modification timestamp.
I may be the reason why repl_gram.c was not rebuilt.

Sorry for the noise.
