RE: gcc 2.8.1 - ported!

I think you might need to update your version of the GNU assembler.
Which version are you currently using ?
(gcc -v should will report version numbers)

	Hello Christian,

	I have problem with this port of GCC 2.8.1 for compiling
programs
	that require floating point computation with the -m68060 option.
	For example This program :

	#include <stdio.h>
	#include <math.h>
	void main()
		{
		double x;
		printf("enter x in degrees : ");
		scanf("%lf",&x);
		printf("\ncos(%lf) = %lf\n",x,cos(x*3.141592654/180.0));
		getc(stdin);
		}

	With this makefile :

	LIBPATH = d:\gnu\gnucc\lib
	INCPATH = d:\gnu\gnucc\include
	GCCEXEC = d:\gnu\gnucc\
	GNULIB = d:\gnu\gnucc\lib
	GNUINC = d:\gnu\gnucc\include
	TEMP = c:\tmp

	CFLAGS=		-c -m68060 -I$(INCPATH) -D__M68881__
	LFLAGS =	-o hello.prg
	CC =            d:\gnu\gnucc\gcc

	# Make's implicit rules for making a .o file from a .c file...
	#
	.c.o :
		$(CC) $(CFLAGS) $*.c


	OBJS = hello.o


	povray:	$(OBJS)
		$(CC) $(LFLAGS) $(OBJS)

	produce the following logfile (output errors) :

	d:\gnu\gnucc\gcc -c -m68060 -Id:\gnu\gnucc\include -D__M68881__

	I am wondering wether there is something to add to the specs
file.
	Is there special library that need to be used for 68060 ? I use
	the inline definition of mathematical functions included in
	math-68881.h. I've updated this file with the one included in
the
	GCC 2.8.1 archive distribution, but it is still not working ...
	Is there something to do ?

	Thanks,
