Merge pull request #2788 in HDFFV/hdf5 from ~LRKNOX/hdf5_lrk:hdf5_1_8 to hdf5_1_8 * commit '4496516ceea24060b966b6b64f4affa2af48eab7': Remove unnecessary assignment freom configure.ac. Check for header szlib.h only when libsz passes AC_CHECK_LIB, so that H5_HAVE_SALIB_H is not defined when szip is not enabled, to prevent compile failures for incompatible szlib.
