You're right, see also one of my previous mails.  They now have POW_DD
and f77_pow_dd (where does this come from, anyway).  I think that in the
``old days'' we were lucky that everything was based on C, so FORTRAN
was converted using f2c and compatibility functions were provided by the
distribution proper.  Of course, in general one cannot expect that ALL
functions needed after using f2c would be in a compatibility library,
unless it was identical to libf2c ...

But clearly, pow_dd and pow_di should exist again ...

O.k., no problem.  As long as there are packages maintained by me
without version numbers ...

Best,
