| 
| On the other hand the is a definition on FreeBSD for 'snprintf' in 
| libc's stdio (/usr/src/lib/libc/stdio/snprintf.c). There is a short hint

| 
| SYNOPSIS
|    #define _WITH_DPRINTF
|    #include <stdio.h>
|       int
|       snprintf(char * restrict str, size_t size,
|                const char * restrict format, ...);
| 
| If this is the same function as meant in 'RcppArmadilloConfig.h' is 
| there any way to integrate it into the package? Please let me know if I 
| can test something.

I do not understand what you are asking: "as meant in RcppArmadilloConfig" ?
Neither Romain, Doug nor I use a *BSD variant (if we ignore OS X as a BSD-derivative).
So nothing in RcppArmadillo explicitly enables or disables *BSD.

You have to tell us what works or doesn't. We cannot test or develop changes
for *BSD.

That patch looks fine to me and would presumabky play nicely with Armadillo
as the change would be solely at our level.  

I'll apply it it now, so 0.2.22 will have it.
