When I compile kernel 2.4.19-pre8 It give 20+ 'Circular' On asm/bitops.h linux/bitops.h, it is probably because they mutually include each other. In the comment in asm/bitops.h I can see that the author know they are mutually included, but solves this by #ifdef guards. Now is there some precompiled directives you can set, so that these dependencies aren't set. -- Martin Hansen Student at SDU Sønderborg. www.sdu.dk Writing final project at Danfoss drives A/S. http://drives.danfoss.com Tlf: 74 88 54 62 -- Kernelnewbies: Help each other learn about the Linux kernel.
