#-----------------------------------------------------------------------------
#   GNU makefile for building PGSBOX 4.3.
#
#   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 pgsbox and
#                 WCSLIB object libraries.
#      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) In compiling the test programs, this makefile assumes that the
#         WCSLIB 4.3 sources reside in ../C and ../Fortran (as in the
#         distribution kit).
