RtsFlags.h

[Sigbjorn Finne]

Defining an app-local version of defaultsHook() is currently
not possible using just a binary distribution. i.e., to do something
interesting inside of defaultsHook(), you need to side-effect
RtsFlags (which has type RTS_FLAGS). RTS_FLAGS is
defined in RtsFlags.h, which is not to be found in a binary
dist.
(=> RtsFlags.h (or a subset thereof) should perhaps be moved
from ghc/rts to ghc/includes/ ?)
