622    ## Intel has conspired to make a supremely environment-sensitive compiler.  The Intel compiler looks at the gcc
623    ## executable in the environment to determine the language compatibility that it should attempt to emulate.  Some
624    ## important Cray installations have built PETSc using the Intel compiler, but with a newer gcc module loaded (e.g.,
625    ## 4.7).  Thus at PETSc configure time, the Intel compiler decides to support the string argument, but the gcc
626    ## found in the default user environment is older and does not support the argument.  If GCC and Intel were cool
627    ## like Clang and supported __has_attribute, we could avoid configure tests entirely, but they don't.  And that is
628    ## why we can't have nice things.
