local float blob = someformula; works now.

added support for -TDP (and #pragma TARGET DP). It is identical to -TFTE except for the instructions used. To be used with Blub's patch when he commits it for DP. It should allow more, this is a first-version.
#if defined(A) && defined(B) will also work as expected. Careful with nesting however, as complex formulas will not. Please use only a single operator.
