Here are some files form other packages that I have changed.

tc-i386.h & tc-i386.c (gas-2.2/gas/config/tc-i386.?)
These file implements code insertion. Copy them, if you have gas sources.

i386.h (gas-2.2/gas/include/opcodes/i386.h)
code insertion(2). I have added one filed in the template structure. So, if
you use this file with another package (e.g. gdb), see tc-i386.h

ld.diff is a patch for ld.c (ld-1.9l.3 from HJ)

libc.chkr.diffs is a patch for libc4.5.21.tgz
