[LLVMdev] dragonegg vs -ffast-math?

  I am finding that llvm 2.8 rc3 with dragonegg svn built against current
gcc-4_5-branch doesn't appear to allow gfortran to use -ffast-math. Attempting
to compile code using the dragonegg plugin under gcc 4.5.2  with that option produces the error...

f951: Unknown command line argument '--enable-finite-only-fp-math'.  Try: 'f951 -help'

The standard gcc 4.5.2 gfortran compiler has no problem with that option.
