# Makefile for gcc (and MinGW, and clang)
# Usage: make [CLANG=Y] [XCOMPILE=Y] [MSWIN=Y] [tgt]
#
# [all|asc2eph|dump_eph|eph2asc|ftest|merge_de|testeph|sub_eph]
#
# Note 'all' does _not_ build 'sub_eph'. 'sub_eph', depends on the 'lunar'
# library, available at https://github.com/Bill-Gray/lunar . Get that,
# make and 'make install' it, and _then_ do 'make sub_eph' if you really
# need the ability to extract a section of a DE ephemeris file.
#
# 'XCOMPILE' = cross-compile for Windows, using MinGW, on a Linux/BSD box
# 'MSWIN' = compile for Windows, using MinGW, on a Windows machine
# 'CLANG' = use clang instead of GCC; Linux/BSD only
# None of these: compile using g++ on Linux or BSD
