Description:
XL compilers in ostrich (PowerPC64 linux) fail in test/dt_arith
because of the removal of the LLONG_TO_LDOUBLE_CORRECT (removed in
r26625) and LDOUBLE_TO_LLONG_ACCURATE (removed in r26623).
Solution:
Reverse revisions
r26623: bring back LDOUBLE_TO_LLONG_ACCURATE configure macro
r26625: bring back LLONG_TO_LDOUBLE_CORRECT configure macro
r26627: bring back WANT_DATA_ACCURACY configure macro which is
used together with the above two macros. This also brings
back the enable-dconv-accuracy configure option.
Tested:
h5committested.
Also tested in ostrich using the XL compilers.
