Subject: Refine the @cast-with-header syntax

The special syntax to generate a module for type information is now:
- "kernel<path/to/header.h>" to use the kernel's build environment
- "<path/to/header.h>" to use no special build environment, and so use
  gcc's default parameters only (for user mode).
