This looks a *whole* lot like the problems in this thread: http://archives.postgresql.org/pgsql-hackers/2005-11/msg00066.php specifically http://archives.postgresql.org/pgsql-hackers/2005-11/msg00104.php So my suggestion is to get rid of that -mcpu=970, and maybe some more of the -m flags too, until you don't get any definition of "bool" in the output from $ echo >foo.c $ gcc -E -dM <<all your other CFLAGS>> foo.c regards, tom lane
