What version of systemtap headers and gcc are you using, that produce this error?
I use RHEL6RC, and the version of systemtap headers and gcc are:
# rpm -qa 'systemtap*' systemtap-sdt-devel-1.2-9.el6.x86_64
but you are using 1.2. The older we go, the worse the systemtap headers were, apparently. Unfortunately, I don't currently have a machine with headers that old to debug it myself.

If a cast really helps matters, I'd almost rather hide it within the #define PROBE() than make callers have to worry about it, but I'm reluctant to add a cast without knowing exactly why you are hitting compilation failure.
