All HAVE_* macros should be tested with #if, not #ifdef.

* configure: In several config tests, test HAVE_SUPERLONG_T,
HAVE_LONGLONG_T and HAVE_SYS_WAIT with #if.

* lib.c: Test HAVE_GETENVIRONMENTSTRINGS with #if.

* lib.h: Test HAVE_DOUBLE_INTPTR_T with #if.

* mpi/mpi.c: Likewise.

* mpi/mpi.h: Likewise.

* socket.c: Test HAVE_GETADDRINFO with #if in three places.

* stream.c: Test HAVE_SYS_WAIT and HAVE_SOCKETS with #if.
