Hi, --8<---------------cut here---------------start------------->8--- #ifdef ERROR_CHECK_MALLOC [...] #define MALLOC_BEGIN() \ do \ { \ assert (!in_malloc); \ assert (!regex_malloc_disallowed); \ in_malloc = 1; \ } \ while (0) [...] #else /* ERROR_CHECK_MALLOC */ #define MALLOC_BEGIN(block) [...] #endif /* ERROR_CHECK_MALLOC */ --8<---------------cut here---------------end--------------->8--- When ERROR_CHECK_MALLOC defined, compiling is ok - MALLOC_BEGIN is running whithout args in functions xmalloc() and xcalloc(). When is not defined, XEmacs is not compiled. 2005-02-23 Andrey Slusar <anrays(a)gmail.com&gt; * alloc.c (MALLOC_BEGIN): MALLOC_BEGIN is not reguire arg `block'.
