#-----------------------------------------------------------------------------
#   GNU makefile for building the WCSLIB 4.3 FORTRAN wrappers.
#
#   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.
#      check (or test): Compile and run the test programs.
#      tests:     Compile the 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.
#
#      2) This makefile assumes that the WCSLIB 4.3 sources reside in ../C
#         (as in the distribution kit).
#
#      3) twcstab assumes that ../C/wcstab.fits has already been generated by
#         the corresponding C test program.
