When building on Solaris 10 SPARC, I see several messages like this:
/rootpool2/local/kirkby/emacs-23.2/lib-src/emacsclient.c:1290:17: warning:
incompatible implicit declaration of built-in function 'alloca'
Note the man page for Solaris says its defined in <alloca.h>
Here's part of the man page
kirkby@t2:64 ~$ man alloca
Standard C Library Functions malloc(3C)
NAME
malloc, calloc, free, memalign, realloc, valloc, alloca -
memory allocator
SYNOPSIS
#include <stdlib.h>
void *malloc(size_t size);
void *calloc(size_t nelem, size_t elsize);
void free(void *ptr);
void *memalign(size_t alignment, size_t size);
void *realloc(void *ptr, size_t size);
void *valloc(size_t size);
#include <alloca.h>
void *alloca(size_t size);
DESCRIPTION
The malloc() and free() functions provide a simple,
general-purpose memory allocation package. The malloc()
function returns a pointer to a block of at least size bytes
suitably aligned for any use. If the space assigned by mal-
loc() is overrun, the results are undefined.

I suspect this is the same as bug#6170
(http://debbugs.gnu.org/cgi/bugreport.cgi?bug=6170) which is
fixed in the trunk release, however the fix has not propagated
back into the emacs-23 branch.

I just backported it. Thanks for the timely reminder.
