    math.c: fix tgamma on mingw
    
    * math.c (mingw_tgamma): tgamma(3) on mingw returns a NaN for a
      big number, not infinity.
    * math.c (ruby_tgamma): fix tgamma(-0.0) on mingw.
      [ruby-core:74817] [Bug #12249]
    
    * math.c (ruby_lgamma_r): fix lgamma(-0.0) on mingw and OSX.
    
    * math.c (ruby_lgamma_r): mswin's lgamma_r also seems to be wrong.
      cf. [Bug #12249]
    
    * math.c (ruby_lgamma_r): missing/lgamma_r.c is used on Windows,
      since msvcrt does not provide it.
    
    * missing/lgamma_r.c (lgamma_r): fix lgamma(-0.0).
      [ruby-core:74823] [Bug #12249]
    
    * configure.in (rb_cv_lgamma_r_m0): check if lgamma_r(-0.0)
      returns negative infinity.  [Bug #12249]
    
    * math.c (ruby_lgamma_r): define by the configured result.
    
    * configure.in (rb_cv_lgamma_r_m0): fix the condition for
      lgamma_r(-0.0).  [Bug #12249]
