It is a simple matter of porting. The code is already ported to GNU libc,
*BSD, MacOS X, AIX, HP-UX, IRIX, OSF/1, Solaris, Cygwin, mingw, BeOS, uClibc.

This is a theoretical argumentation. coreutils, emacs, Perl all rely on
internal fields of FILE that are not specified by POSIX.
  coreutils     for closing streams reliably
  emacs         PENDING_OUTPUT_COUNT macro
  Perl          see perlio.c
