OK. It was late in my day. I was wrong about the callout - as the
default is "no callout", the same trick isn't relevant. Also, the two
kinds of malloc default to the same thing, so we only need two
functions, not four. So we are left with this:

-------------------------------------------------------------------
#ifdef _WIN32
#include <malloc.h>

void* malloc_stub(size_t N)
{ return malloc(N); }

void free_stub(void* p)
{ free(p); }

void *(*pcre_malloc)(size_t) = &malloc_stub;
void (*pcre_free)(void *) = &free_stub;
void *(*pcre_stack_malloc)(size_t) = &malloc_stub;
void (*pcre_stack_free)(void *) = &free_stub;

#else

void *(*pcre_malloc)(size_t) = malloc;
void (*pcre_free)(void *) = free;
void *(*pcre_stack_malloc)(size_t) = malloc;
void (*pcre_stack_free)(void *) = free;

#endif


int (*pcre_callout)(pcre_callout_block *) = NULL;
-------------------------------------------------------------------


But whether that will help at all, I don't know.
