This whole discussion misses the point. The reason I changed the
code back to regular c from c99 is because the code did not compile.
This happened because rump did not pass -std=gnu99 in the compiler
flags. Now I did 'for (size_t i = 0;' in sys/crypto and the regression
tests failed. If we are going to be compiling the kernel in c99
mode, then I suggest that we do the same for userland instead of
turning it on for userland piecemeal.
