commit b638f96a7607a279d5fd9b14fb49e02fa5151b5f
Author: Chris Metcalf <cmetcalf@ezchip.com>

    Fix namespace conformance issue with Bessel functions.
    
    [BZ #17747]
    The y0/y1/yn and j0/j1/jn functions provided a strong_alias
    to the "l"-suffixed variants when no long double support is
    being compiled.  This breaks namespace conformance when the
    basename versions conform but the l-suffixed ones don't.
    Fixed by making them weak aliases instead.
