Taking a second look at this and noticing some past post about this issue
with WinXP (http://news.lugnet.com/robotics/rcx/legos/?n=2470) a much
cleaner code might look like the following
#
# WindowsNT/Cygnwin, test against several values:
#
ifneq (,$(findstring $(OSTYPE),cygwin32 cygwin WindowsNT
Windows_NT)||$(findstring CYGWIN,$(OSTYPE)))
EXT=.exe
CC =gcc
CFLAGS+=-D_WIN32
endif
