   228  //    for many years.  We now treat them as compatibility synonyms for

   238  // GNU formerly extended the scanf functions with modified format
   239  //    specifiers %as, %aS, and %a[...] that allocate a buffer for the
   240  //    input using malloc.  This extension conflicts with ISO C99, which
   241  //    defines %a as a standalone format specifier that reads a floating-
   242  //    point number; moreover, POSIX.1-2008 provides the same feature
   243  //    using the modifier letter 'm' instead (%ms, %mS, %m[...]).
   244  //
   245  //    We now follow C99 unless GNU extensions are active and the compiler
   246  //    is specifically in C89 or C++98 mode (strict or not).  For
   247  //    instance, with GCC, -std=gnu11 will have C99-compliant scanf with
