dovecot - Apr 2013 - failed compiling dovecot 2.1.16 under solaris

Hello,

compiling doevoct-2.1.16 with sun-compiler under solaris 10 gave me the
following error

source='quota-status.c' object='quota-status.o' libtool=no \
          DEPDIR=.deps depmode=none /bin/bash ../../../depcomp \
          cc -DHAVE_CONFIG_H -I. -I../../..  -I../../../src/lib

"quota-status.c", line 200: undefined symbol: optarg
"quota-status.c", line 200: warning: improper pointer/integer

cc: acomp failed for quota-status.c

I could solve this problem with

*** ./src/plugins/quota/quota-status.c.orig     Thu Apr  4 22:58:30 
2013
--- ./src/plugins/quota/quota-status.c  Tue Apr  9 16:08:12 2013
***************
*** 11,16 ****
--- 11,17 ----
    #include "mail-storage-service.h"
    #include "quota-private.h"
    #include "quota-plugin.h"
+ #include <stdlib.h>

    enum quota_protocol {
          QUOTA_PROTOCOL_UNKNOWN = 0,

but I don't know if this is the correct way to fix it.

Greetings,
J?rgen

What about with stdio.h? That's the correct one according to man page.
