Remove Precompiled Headers from Repository
Remove Precompiled Headers from Repository

File dfutil-Prefix.pch is a platform-specific precompiled Header file
that is a hangover from before *.pch being added to .gitignore.

Precompiled headers are probably not important for these small compiles.
They should probably only occur in build/ even then, and not be carried
in the public repo.
