Marcel Hlopko 9bb9b737c5 Remove HAVE_VCS_VERSION_INC, not needed
This preprocessor define was meant to be used to conditionally include VCSVersion.inc. However, the define was always set, and it was the content of the header that was conditionally generated. Therefore HAVE_VCS_VERSION_INC should be cleaned up.
