#-----------------------------------------------------------------------------
#   GNU makefile for building WCSLIB 4.3 and its test suite.
#
#   Summary of the main targets
#   ---------------------------
#      build:     Build the library.
#      clean:     Delete intermediate object files.
#      cleaner:   clean, and also delete the test executables.
#      realclean (or cleanest): cleaner, and also delete the object library
#                 the C source files generated by 'flex', and wcsconfig.h and
#                 wcsconfig_test.h which are generated by 'configure'.
#      check (or test): Compile and run the test programs.
#      tests:     Compile the test programs (but don't run them).
#      check_s:   Compile and run the scalar test programs.
#      tests_s:   Compile the scalar test programs (but don't run them).
#
#   Notes:
#      1) If you need to make changes then preferably modify ../makedefs.in
#         instead and re-run configure.
