CVS head doesn't compile

I'm seeing this on CVS head:

make[4]: Entering directory
`/home/alvherre/CVS/pgsql/src/backend/access/common'
distcc -O2 -g -Wall -Wmissing-prototypes -Wmissing-declarations
-I../../../../src/include -c -o printtup.o printtup.c -MMD

make[1]: Leaving directory `/home/alvherre/CVS/pgsql/src'
make: *** [all] Error 2

Apparently this is a flaw in configure, because it detects getaddrinfo
but fails to define HAVE_GETADDRINFO in pg_config.h, and it works if I
define the symbol manually.
