  functions on OS X 10.8 and earlier when called from plain inline
  or extern inline functions.

  POSIX specification:@* @url{http://www.opengroup.org/onlinepubs/9699919799/functions/isblank.html}
  
  Gnulib module: isblank
  
  Portability problems fixed by Gnulib:
  @itemize
  @item
  This function is missing on some platforms:
  AIX 4.3.2, IRIX 6.5, OSF/1 5.1, Solaris 9, mingw, MSVC 9.
  @item
  This function cannot be called from plain inline or extern inline functions
  on some platforms:
  OS X 10.8.
  @end itemize
  
  Portability problems not fixed by Gnulib:
  @itemize
  @end itemize
  
  Note: This function's behaviour depends on the locale, but does not support
  the multibyte characters that occur in strings in locales with
  @code{MB_CUR_MAX > 1} (this includes all the common UTF-8 locales).
  There are four alternative APIs:
  
  @table @code
  @item c_isblank
  This function operates in a locale independent way and returns true only for
  ASCII characters.  It is provided by the Gnulib module @samp{c-ctype}.
  
  @item iswblank
  This function operates in a locale dependent way, on wide characters.  In
  order to use it, you first have to convert from multibyte to wide characters,
  using the @code{mbrtowc} function.  It is provided by the Gnulib module
  @samp{wctype}.
  
  @item mb_isblank
  This function operates in a locale dependent way, on multibyte characters.
  It is provided by the Gnulib module @samp{mbchar}.
  
  @item uc_is_blank
  This function operates in a locale independent way, on Unicode characters.
  It is provided by the Gnulib module @samp{unictype/ctype-blank}.
  @end table
