More accurately, compiling a kernel with "pgcc" instead of "gcc" makes
for a *different* kernel. Instructions, and their order, change. As
a result, bugs behave differently, causing failures once an hour with
the "gcc" kernel and once a year with the "pgcc" kernel.
However, it wouldn't be wise to generalize. A different kind of bug
might make "gcc" produce a "stabler" kernel than "pgcc".
