423 /* _GL_WARN_ON_USE (function, "literal string") issues a declaration
424    for FUNCTION which will then trigger a compiler warning containing
425    the text of "literal string" anywhere that function is called, if
426    supported by the compiler.  If the compiler does not support this
427    feature, the macro expands to an unused extern declaration.
428 
429    _GL_WARN_ON_USE_ATTRIBUTE ("literal string") expands to the
430    attribute used in _GL_WARN_ON_USE.  If the compiler does not support
431    this feature, it expands to empty.
432 
433    These macros are useful for marking a function as a potential
434    portability trap, with the intent that "literal string" include
435    instructions on the replacement function that should be used
436    instead.
437    _GL_WARN_ON_USE is for functions with 'extern' linkage.
438    _GL_WARN_ON_USE_ATTRIBUTE is for functions with 'static' or 'inline'
439    linkage.
440 
441    However, one of the reasons that a function is a portability trap is
442    if it has the wrong signature.  Declaring FUNCTION with a different
443    signature in C is a compilation error, so this macro must use the
444    same type as any existing declaration so that programs that avoid
445    the problematic FUNCTION do not fail to compile merely because they
446    included a header that poisoned the function.  But this implies that
447    _GL_WARN_ON_USE is only safe to use if FUNCTION is known to already
448    have a declaration.  Use of this macro implies that there must not
449    be any other macro hiding the declaration of FUNCTION; but
450    undefining FUNCTION first is part of the poisoning process anyway
451    (although for symbols that are provided only via a macro, the result
452    is a compilation error rather than a warning containing
453    "literal string").  Also note that in C++, it is only safe to use if
454    FUNCTION has no overloads.
455 
456    For an example, it is possible to poison 'getline' by:
457    - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
458      [getline]) in configure.ac, which potentially defines
459      HAVE_RAW_DECL_GETLINE
460    - adding this code to a header that wraps the system <stdio.h>:
461      #undef getline
462      #if HAVE_RAW_DECL_GETLINE
463      _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
464        "not universally present; use the gnulib module getline");
465      #endif
466 
467    It is not possible to directly poison global variables.  But it is
468    possible to write a wrapper accessor function, and poison that
469    (less common usage, like &environ, will cause a compilation error
470    rather than issue the nice warning, but the end result of informing
471    the developer about their portability problem is still achieved):
472      #if HAVE_RAW_DECL_ENVIRON
473      static char ***
474      rpl_environ (void) { return &environ; }
475      _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
476      # undef environ
477      # define environ (*rpl_environ ())
478      #endif
479    or better (avoiding contradictory use of 'static' and 'extern'):
480      #if HAVE_RAW_DECL_ENVIRON
481      static char ***
482      _GL_WARN_ON_USE_ATTRIBUTE ("environ is not always properly declared")
483      rpl_environ (void) { return &environ; }
484      # undef environ
