The R-admin manual did tell you not to do that!

   When using the Sun compilers do @emph{not} specify @option{-fast}, as
   this disables @acronym{IEEE} arithmetic and @command{make check} will
   fail.

That was for Solaris and SunStudio 11, but I presume these are basically 
the same compilers.  (--fast has been a no-no for as long as I have been 
using R on Solaris, ca 10 years.)
