  isfinite: Work around a bug with 'long double' in glibc 2.5/ia64.
  
  * m4/isfinite.m4 (gl_ISFINITEL_WORKS): Require
  gl_LONG_DOUBLE_EXPONENT_LOCATION. Test also another NaN value.
  * modules/isfinite (Files): Add m4/exponentl.m4.
  * doc/posix-functions/isfinite.texi: Mention also a 'long double'
  problem on ia64.
