#
|
|
# Special targets:
|
|
#
|
|
# clean - remove executables and objects for this build
|
|
# cleandep - remove dependency files for this build
|
|
# distclean - remove entire executable, object and
|
|
# dependency file directory structure.
|
|
# dump - disassemble executable
|
|
# info - print settings
|
|
#
|
|
# This Makefile can automatically detect the host system
|
|
# as well as the compiler version. If system or compiler
|
|
# version cannot be detected, you may need to set a flag
|
|
# manually.
|
|
#
|
|
# On Windows machines, 32-bit Windows is always targetted.
|
|
#
|

|
# FREEBSD=1
|
|
# SDL=1 - Use SDL backend. SDL is the only backend though
