408 /* _GL_WARN_ON_USE (function, "literal string") issues a declaration
409  for FUNCTION which will then trigger a compiler warning containing
410  the text of "literal string" anywhere that function is called, if
411  supported by the compiler. If the compiler does not support this
412  feature, the macro expands to an unused extern declaration.
413 
414  This macro is useful for marking a function as a potential
415  portability trap, with the intent that "literal string" include
416  instructions on the replacement function that should be used
417  instead. However, one of the reasons that a function is a
418  portability trap is if it has the wrong signature. Declaring
419  FUNCTION with a different signature in C is a compilation error, so
420  this macro must use the same type as any existing declaration so
421  that programs that avoid the problematic FUNCTION do not fail to
422  compile merely because they included a header that poisoned the
423  function. But this implies that _GL_WARN_ON_USE is only safe to
424  use if FUNCTION is known to already have a declaration. Use of
425  this macro implies that there must not be any other macro hiding
426  the declaration of FUNCTION; but undefining FUNCTION first is part
427  of the poisoning process anyway (although for symbols that are
428  provided only via a macro, the result is a compilation error rather
429  than a warning containing "literal string"). Also note that in
430  C++, it is only safe to use if FUNCTION has no overloads.
431 
432  For an example, it is possible to poison 'getline' by:
433  - adding a call to gl_WARN_ON_USE_PREPARE([[#include <stdio.h>]],
434  [getline]) in configure.ac, which potentially defines
435  HAVE_RAW_DECL_GETLINE
436  - adding this code to a header that wraps the system <stdio.h>:
437  #undef getline
438  #if HAVE_RAW_DECL_GETLINE
439  _GL_WARN_ON_USE (getline, "getline is required by POSIX 2008, but"
440  "not universally present; use the gnulib module getline");
441  #endif
442 
443  It is not possible to directly poison global variables. But it is
444  possible to write a wrapper accessor function, and poison that
445  (less common usage, like &environ, will cause a compilation error
446  rather than issue the nice warning, but the end result of informing
447  the developer about their portability problem is still achieved):
448  #if HAVE_RAW_DECL_ENVIRON
449  static char ***rpl_environ (void) { return &environ; }
450  _GL_WARN_ON_USE (rpl_environ, "environ is not always properly declared");
