Is that so problematic ? These are only headers, not programs. IANAL,
but that's fair use, needed for interoperability.
Do I need to retype the constants myself ?
Another option is to compile that extension only on machines where those
headers are installed, but that would limit the usefullness of pre-built
binaries in the distributions.
One could also add a message at run-time telling the user to recompile
from sources, or add a way to check if those files are available and
"compile" them at the first usage of strace, but that's stupid extra work
