Detected and fixed minor issues with the single-source generation:
* On Windows the line info generation now correctly escapes the path separators.
* Fixed an incorrect C file include order. Now the global object C file is
force included to get all common headers at the start in the generated source
file.
* Added a missing colon which fixed the correct removal of the config.h include.
* Fix the command line help.
* Small typo fix.
