      Test compiler and linker flags with AX_COMPILER_FLAGS_* macros · 003e5e68
      Thomas Zimmermann authored
      The autoconf macros AX_COMPILER_FLAGS_{CFLAGS|CXXFLAGS|LDFLAGS} test
      for compiler and linker support of various flags, and add the flags to
      the generated output.
      
      If the command-line option '--enable-compile-warnings' is specified to
      'configure', a number of additional warning options is also added to the
      output. This is the default.
      
      The AX_COMPILER_FLAGS_* macros add stricter warnings then before. The
      patch disables some of them to make dbus build without errors. A later
      patch set should fix the warnings and remove the compiler flags.
      
      This patch integrates all tests for compiler flags into the call to
      AX_COMPILER_FLAGS_CFLAGS. All tests for compiler flags are now done
      in a single place. The old macros have been removed.
