I tried RcppArmadillo_0.2.21.tar.gz with R-devel from today on FreeBSD
9.0-CURRENT (amd64). The build fails with the following messages:

------------------------------------------
Obviously there is something wrong with 'snprintf'. The appended patch
avoids the breakage.
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
in the manpage:
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.
Many thanks in advance,
Rainer Hurling
