Last change on this file since 038713 was 56f73b, checked in by Frederik Heber <heber@…>, 15 years ago

Added config.h also to all header files, code check test ascertain this in the future.

  • as we want to use config.h to pass stuff such as MEMDEBUG, NDEBUG, LOG_OBSERVER, we have to make sure that it is present in each and every file.
  • split up CodeChecks/testsuite.at: each test has its own .at file.
  • Property mode set to 100644
