If a compilation unit #include a header that defines a static inline function,
and that static inline function calls an external function, then even if you do
not use the inline function, the Solaris Studio compiler produces a reference
to that external.  That behavior prevented H5make_libsettings from linking:
H5_nanosleep, used by the h5_retry_ functions, was not found.  #including
H5retry_private.h only where it's needed fixes the issue.
