I know this might have been recommended, but I don't believe it is a good idea
in this case: all of the tests that we do use gcc (not icc) for the C
compiler. Of course, both should work, but you are exposing yourself to new
bugs (in our code, or in the icc compiler) if you do this. My vote is to
stick to gcc.

It's possible that something was not correctly cleaned when you changed
compilers. This error message doesn't seem to show up on a (simple) Google
search, which itself is weird. Unless you are sure that you need the
makeDIST_RST program, you can probably skip this step of compilation (or go
back to gcc as suggested above.
