a) Extending makecontext() on AMD64 so it can pass pointers, and add a section to the manpage to explain that you cannot portably do this, but GNU libc happens to allow it,
This is not possible, as it would break the ABI, something we do not want, and break the compliance to POSIX.
It is possible, as far as passing int is unaffected, all other cases have undefined behaviour in POSIX. In fact, the needed source change is already in glibc 2.8. http://sources.redhat.com/cgi-bin/cvsweb.cgi/libc/sysdeps/unix/sysv/linux/x86_64/makecontext.c.diff?r1=1.5&r2=1.6&cvsroot=glibc But it is not possible to pass ints, longs and pointers in general on all architectures.
