rsync - Apr 2003 - compile 11.00 parisc1.1 32-bit fails - snprintf

I am having trouble compiling rsync 2.5.6 for HPUX 11.00.
The system I am using has a number of patches, although I admit not having
verified that it is completely up to date.
I have found gcc 3.2 and gmake and installed them.

- configure seems to work fine. (my use ./configure
--prefix=/opt/trial/local --with-rsync-path=/opt/trial/local/bin/rsync)

- it finds snprintf and vsnprintf but not C99 vsnprintf
<snip>
checking for vsnprintf... yes
checking for snprintf... yes
checking for asprintf... no
checking for C99 vsnprintf... no
<snip>

- make fails
<snip - all worked up to:>
gcc -I. -I. -g -O2 -DHAVE_CONFIG_H -Wall -W -I./popt  -c lib/snprintf.c -o
lib/snprintf.o
lib/snprintf.c: In function `dopr':
lib/snprintf.c:199: warning: signed and unsigned type in conditional
expression
lib/snprintf.c:219: warning: signed and unsigned type in conditional
expression
lib/snprintf.c: At top level:
lib/snprintf.c:760: error: conflicting types for `snprintf'
/usr/local/lib/gcc-lib/hppa1.1-hp-hpux11.00/3.2/include/stdio.h:459: error:
previous declaration of `snprintf'
*** Error exit code 1

The problem seems to be in lib/snprintf.c :
#if defined(HAVE_SNPRINTF) && defined(HAVE_VSNPRINTF) &&
defined(HAVE_C99_VSNPRINTF)
/* only include stdio.h if we are not re-defining snprintf or vsnprintf */
#include <stdio.h>
 /* make the compiler happy with an empty file */
 void dummy_snprintf(void) {}
#else
<snip>


- if I just run:
gcc -I. -I. -g -O2 -DHAVE_CONFIG_H -DHAVE_SNPRINTF -DHAVE_VSNPRINTF
-DHAVE_C99_VSNPRINTF -Wall -W -I./popt  -c lib/snprintf.c -o lib/snprintf.o
and then make again, it seems to work.

It seems to me I may have some issue with gcc-lib or with missing HPUX
patches, but not too sure.
Am I on the right track here?

Cheers,

I found that after running configure, it was necessary to modify the
config.h file as follows:

replace
      #undef HAVE_C99_VSNPRINTF
with
      #define HAVE_C99_VSNPRINTF 1

You should then be able to compile.
