Bug#482311: luatex: check_isnode() implicitly converted to pointer

[dann frazier <dannf@debian.org>]

Package: luatex
Version: 0.25.2-1
Severity: important
Tags: patch
Usertags: implicit-pointer-conversion

Our automated buildd log filter[1] detected a problem that is likely to
cause your package to segfault on architectures where the size of a
pointer is greater than the size of an integer, such as ia64 and amd64.

  Function `check_isnode' implicitly converted to pointer at ../../../../src/texk/web2c/luatexdir/lua/llanglib.c:168

This is often due to a missing function prototype definition.
For more information, see [2].
