Before I go to sleep, I've shortened the diff by about 50%. The new diff
is at:
http://sharmas.dhs.org/~adsharma/projects/freebsd/truss-diff.gz
http://sharmas.dhs.org/~adsharma/projects/freebsd/truss.tar.gz
To be applied as:
cd truss
gzcat -dc truss-diff.gz | patch -p1
The real 100 lines of changes are:
1. Line 306 in i386-fbsd.c (where all the action starts)
2. Last few lines of main
3. Some changes in syscalls.c:print_syscall
It now prints syscalls one per line, like linux and solaris equivalents.
The Makefile changes can be completely ignored. They are there so that
truss can be compiled in a directory other than /usr/src.
