You must be using a very old "petsc-dev".  Likely scenario here is that
you have changed environments from when you configured, and now this
older version of gcc (the Intel compiler changes its dialect based on
which gcc it finds in path) has a dialect that doesn't support arguments
to attribute deprecated.  This was so common that I unconditionally
turned off use of the argument to attribute deprecated.  (Yes, this is
worse for users that have a stable environment or don't use Intel
compilers, but Intel's indirect environment-dependence causes the
unacceptable breakage above so we had to work around it somehow.)
