#-----------------------------------------------------------------------------
# Variable definitions for various combinations of architecture, operating
# system, compiler, and purpose. Used for development and testing only, not
# required for building WCSLIB.
#
# Definitions in this file are only used when running 'configure'. Variables
# such as CC and CFLAGS are exported to the environment so that they will be
# seen by 'configure' and from there passed to makedefs. Thus, normal usage
# is as follows:
#
# make distclean
# make FLAVOUR=dev configure
#
# At that point the definitions here should have propagated to makedefs.
#
# WARNING: configure may ignore compiler options added to the CC or F77
# environment variables. They must be added to CFLAGS or FFLAGS.
#
# Reminder: add '-d' to FLFLAGS for debugging.
