Is this a new version of G95?  GFortran 4.5.0 needs -Wno-line-truncation
because of

  http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42852

I don't know if there is much code sharing between G95 and GFortran
these days.

What does this path have to with anything?  Does mkstemp give you
temporary files in places like that on a Mac?  I don't understand where
the subtraction could occur, but perhaps the assembly in this file holds
clues?
