suggested fix (non-snprintf-having machines)

[Lincoln DeCoursey]

Gentlemen,

I was able to correct a compilation error by replacing some code.

When attempting to build INN 2.4.1 on HP-UX 10.20 using gcc 2.95.2,
I received the following error:

gcc -g -O2 -I../include   -c setproctitle.c
In file included from setproctitle.c:16:
../include/clibrary.h:110: wrong number of arguments specified for
`__format__'
attribute
gmake[1]: *** [setproctitle.o] Error 1
gmake[1]: Leaving directory `/usr/local/news/temp/inn-2.4.1/lib'
gmake: *** [all-lib] Error 2

Take a look at include/clibrary.h at line 109:

#if NEED_DECLARATION_SNPRINTF
extern int              snprintf(char *, size_t, const char *, ...)
    __attribute__((__format__(3, 4)));
#endif

I changed this to:

#if NEED_DECLARATION_SNPRINTF
 extern int snprintf(char *str, size_t size, const char *format, ...);
#endif

Honestly, I have no idea what this code accomplishes, except that
in general I understand the goal of snprintf, and that my operating
system version doesn't seem to have it.

I suspect that in your development effort, you work on more modern
systems, and therefore may not be aware of the build failure which
evidences itself in this situation.

I got the idea for this modification from a gentleman who had hacked
abiword sources to satisfy a snprintf dependancy.

Anyway, this is the first time I have ever attempted to hack "real"
software.  So, please forgive me if there is not really a problem
with your code, but rather with my environment.  However, since I
enjoyed success with this substitution, I though you might be
interested to know.
