[svn-r134] Changes since 19971023
----------------------
./config/conclude.in
Test work when `.' isn't in $PATH.
./src/H5F.c
./src/H5Fcore.c NEW
./src/H5Flow.c
./src/H5Fprivate.h
./src/H5Fsec2.c
./src/H5Fstdio.c
./src/Makefile.in
./MANIFEST
Added the in-core temporary file driver as an exercise to
clean up some of the H5F package. It speeds up `testhdf5 -o
stab' by 25 percent! If you want to try it you'll need to
recompile everything with `-DH5F_LOW_DFLT=H5F_LOW_CORE'.
Don't expect testhdf5 to ever work since creating a file,
closing it, and then opening it for read-only will fail.
