>Description:
	

	During make, compiled and linked cyclone tries to compile bison/main.cyc
	cyclone segfaults

	
>How-To-Repeat:
	

	Download http://www.research.att.com/projects/cyclone/cyclone-0.2.tar.gz
	Then do the following : 
	tar zxf cyclone-0.2.tar.gz
	cd cyclone
	./configure
	vi Makefile.inc
		(change CC variable to be gcc-3.0, then save file and exit vi)
	make

	Then you see this :
	make[1]: Entering directory `/disk1/home/mwg/cyclone/cyclone/tools/bison'
	/disk1/home/mwg/cyclone/cyclone/bin/cyclone  -I/disk1/home/mwg/cyclone/cyclone/include -B/disk1/home/mwg/cyclone/cyclone/bin/cyc-lib  -c main.cyc
	make[1]: *** [main.o] Segmentation fault
	make[1]: Leaving directory `/disk1/home/mwg/cyclone/cyclone/tools/bison'
	make: *** [tools] Error 2

	I tried to debug this, but without much success. I did not understand its logic completely enough, so I was unable to compose short enough testcase for gcc-3.0
	
>Fix:
	

	Compiling with gcc-2.95.4 works well. People from AT&T say that gcc-3.0 will not work.
