message: Remove '/experimental:preprocessor' compiler switch
diff: -if (MSVC)
  - # The MSVC compiler doesnt comply to c99 thus the OATPP_MACRO_HAS_ARGS macro always expands to 1
  - # This screws up the DTO_FIELD and ENDPOINT macros. To force MSVC to c99 compliant mode we need to activate this
  - # experimental switch. However, we can't enable it globally since the Windows-SDK isn't prepared for this and
  - # throws a whole bunch of errors.
