x86_64 Scientific Linux 5.7
I am compiling on 32-bit, not 64-bit. Perhaps that is the difference.
The system has
I have exactly those same values in the same headers. However, running
gcc -dD -E on alloc.c (after configuration, with all the same args as
used for compilation) shows that those values are not being used.
Instead, Emacs's (gnulib's) lib/stdint.h is being used (why?), which
unconditionally redefines PTRDIFF_MAX as _STDINT_MAX, which is defined
in that same file as the RHS here (the LHS is the recognizable value of
INT_MAX):
_Static_assert (2147483647 <= ((1) ? ~ ((1) ? (- ((0) + 1) << ((0) ? (0) - 1 :
0)) : (0)) : ((((0) + 1) << ((0) ? (0) - 1 - (1) : 0)) - 1) * 2 + 1), "verify
(" "INT_MAX <= PTRDIFF_MAX" ")");
FWIW, if I reduce the input file to these four lines:
#include <config.h>
#include "lisp.h"
#include <verify.h>
verify (INT_MAX <= PTRDIFF_MAX);
And compile with all the same options, I get the same error from verify
(along with a spurious error about jmp_buf). Without "lisp.h",
PTRDIFF_MAX is not defined.
Here is my full command line:
