You have to rebuild the auto-generated pgc.c, preproc.c and preproc.y or simply
remove them to force a rebuild.

Thanks, seems it is because the first time pgc.c and others are generated, but [make distclean] did not clean them, which lead to this problem!
after [rm pgc.c preproc.h preproc.c preproc.y]
it is now successfully compiled without any warning! thank you!

maintainer-clean removes those, distclean doesn't because they are
distributed so people without flex/bison can compile postgres.
