That looks like a real problem, but it seems to be cleaned up already
in HEAD.

These all seem to relate to uses of PTHREAD_ONCE_INIT, which is a
system-provided macro --- so I think you need to complain to Sun
that their headers provide warning-inducing declarations.  It should
be just cosmetic as far as functionality goes, though.

This one probably is because of a discrepancy in "const" decorations of
parameters for the PAM callback proc.  Again, it's cosmetic, and seems
more likely to indicate obsolete Solaris headers than anything we should
change on our end.
