[MiNT] About SPECS of GCC 2.91.66

[LE COAT Francois <lecoat@ief.u-psud.fr>]

Hi All,

When I try to compile the following program :

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

I have the following report :

What does mean the "Using builtin specs". Does it mean that the SPECS
file is
not read ? Would it explain that the -mc68000 option is passed to as
(the
assembler) ? In any way, I use a correct SPECS file, where should it
be located ? The one that is included in the 2.91.66 release is not
correct for supporting 68060 architecture. I have an HADES 060, and
there soon be a MILAN 060. So, read obout it !

Regards,
Bye for now ...
