  Gnulib module: isfinite
  
  Portability problems fixed by Gnulib:
  @itemize
  @item
  This macro is missing on some platforms:
  macOS 11.1, OpenBSD 6.7, AIX 5.1, IRIX 6.5, Solaris 11.4.
  @item
  This macro incorrectly yields true for some @samp{double} arguments, on some
  platforms:
  Linux/ia64 (signalling NaNs).
  @end itemize
  
  Portability problems not fixed by Gnulib:
  @itemize
  @item
  It is implementation-dependent whether @code{isfinite} raises an
  exception given a signaling NaN operand.
  @item
  This macro returns an unspecified result when given noncanonical values
  such as unnormalized numbers, pseudo-denormals, pseudo-NaNs,
  pseudo-Infinities, and pseudo-zeroes.
  @end itemize
