[ECOS] how to apply the patches for i386

[niky]

Hi,

I got the patches Fabrice Gautier provides for i386 from

    ftp://ftp.sigmadesigns.com/ecos/

when I used the patch hal-i386-pc.patch under the packages diretory

    patch -r0 < hal-i386-pc.patch

it showed

can't find file to patch at input line 9
Perhaps you should have used the -p or --strip option?
The text leading up to this was:
--------------------------
|? hal/i386/pc/current/include/plf_io.h
|Index: hal/i386/arch/current/include/basetype.h
|===================================================================
|RCS file:
/cvs/ecos/ecos/packages/hal/i386/arch/current/include/basetype.h,v
|retrieving revision 1.7
|diff -u -w -b -B -r1.7 basetype.h
|--- basetype.h 2000/09/05 15:44:11 1.7 
|+++ basetype.h 2000/11/02 20:50:30
--------------------------
File to patch:

it could not find the file basetype.h, but
    hal/i386/arch/current/include/basetype.h really exists.
Patch finds the basetype.h according to Index, doesnt it ?
How could I apply the patch ?
Thanks for your help!
