Hi Erik,
i've finaly found some time to check your second problem.

I knew that one day i'll get this question :)
One of the reasons that made me starting PMK was the problem that
occured some time ago with trojans hidden in configure scripts. The
solution in my mind was to replace scripts by data files. So the threat
is located only in pmk code instead of every configure scripts.

Until now we always found an alternative for AC_TRY_RUN and i hope we'll
always succeed in that :)
I've looked quickly at your m4 macro so i get the main idea of what
you're checking. Now i'm wondering if this is a bug or a feature, could
you provide me an URL that explain a bit more this phenomenon ?
