Hi, Dave,

The ISL is used after gcc-4.8.

>From the gcc-4.4.0 souce, gcc/doc/install.text,
the prerequisites are:
  gmp 4.1
  mpfr 2.3.2
  ppl 0.10
  cloog-ppl 0.15

Also, if I remember correctly, the in-tree build of ppl and cloog-ppl
didn't work very well.  So if your are forced to build gcc-4.4.0, either
dropping ppl/cloog-ppl or build them by your own with required version.
