105* tracing setuid programs works better
106* it is now reasonable to install strace setuid to root in some circumstances

109 take a file name as an argument
110* IPC calls on SunOS 4.1.x are decoded
111* Linux program memory is reliably dereferenced
112* Linux decodes at least the name of all syscalls as of pre2.0.4

121* by default the output for multiple processes now goes into one file
122* all structures, vectors, bitsets, etc. use consistent output formats
