Description:
if running the configure script on SunOS4 the following WARNING occurs:

./configure `cat /export/home/klausz/src/conf_bash-4.3.30`

this leads to the following compilation errors later on:

Hi Chet,

I have no clue how to fix the bashversion linking error in the configure 
script, besides modifying config.h after
configure has done it's work. However, the compile error in 
execute_cmd.c, is directly related to the failed
autoconf test for <sys/resource.h> from above. On SunOS4 a test for 
/usr/include/sys/resource.h needs to
include /usr/include/sys/time.h to be successful.

from config.log:
configure:9287: checking sys/resource.h usability
configure:9287: gcc -c -O2  conftest.c >&5
In file included from conftest.c:147:
/usr/include/sys/resource.h:24: field `ru_utime' has incomplete type
/usr/include/sys/resource.h:25: field `ru_stime' has incomplete type
configure:9287: $? = 1

from /usr/include/sys/resource.h:
     23  struct  rusage {
     24          struct timeval ru_utime;        /* user time used */
     25          struct timeval ru_stime;        /* system time used */
from /usr/include/sys/time.h:
     16  struct timeval {
     17          long    tv_sec;         /* seconds */
     18          long    tv_usec;        /* and microseconds */
     19  };
including <sys/time.h> before checking <sys/resource.h> works.

sorry it's the newest one I could find for this platform.

Repeat-By:
tried 4.1 series - also happens there.


Fix:
quick fix: change config.h after configure is run:

diff config.h.orig config.h
782c782
< #define HAVE_SNPRINTF 0
---
 > /* #undef HAVE_SNPRINTF */
1000c1000
< /* #undef HAVE_SYS_RESOURCE_H */
---
 > #define HAVE_SYS_RESOURCE_H 1

I don't have the whole autoconf stuff running on this old Sun 3/80, 
therefore only the
configure patch, not a configure.ac patch, sorry about that.

Much Regards
Klaus
