GNU Mach 1.x fixes |

The following fixes the GNU Mach 1 branch so that it can compile with
recent versions of gcc (>3.x) and binutils (>2.14)
2004-01-15 Alfred M. Szmidt <ams@kemisten.nu
* linux/src/drivers/scsi/53c7,8xx.h (patch_dsa_32): Don't use
token paste operator (##).
* linux/dev/include/asm-i386/string.h (memscan): Don't use
multi-line string literals for asm().
* linux/dev/include/asm-i386/segment.h (__generic_memcpy_tofs)
(__generic_memcpy_fromfs): Likewise.
* i386/i386/proc_reg.h (flush_instr_queue): Likewise.
* i386/i386/gdt.c (gdt_init): Likewise.
* Makefile.in (kernel-undef): Match new output format form
nm (binutils) 2.14.x.
