COMPILER: --enable-c++11 breaks compilation in commandline.cpp (AmigaOS4)

Description (last modified by )
Using the flag
--enable-c++11
with configure, makes the compiler error early in commandline.cpp.
C++ base/commandLine.o
base/commandLine.cpp: In function 'void Base::usage(const char*, ...)':
base/commandLine.cpp:162:36: error: 'vsnprintf' was not declared in this scope
vsnprintf(buf, STRINGBUFLEN, s, va);
^
gmake: *** [base/commandLine.o] Error 1
The same (or at least something similar) happens when using the flag
-std=c++11
on a test program.
#include <stdio.h>
#include <stdarg.h>
void test() { va_list ap; vsnprintf(0, 0, 0, ap); }
Building it with
g++ -c -o test.o test.cpp
works fine, but adding the c++11 flag and using
g++ -c -o test.o test.cpp -std=c++11
throws this error
test.cpp: In function 'void test()':
test.cpp:5:48: error: 'vsnprintf' was not declared in this scope
void test() { va_list ap; vsnprintf(0, 0, 0, ap); }

Not broken, it seems it's not yet supported: https://github.com/sba1/adtools/issues/6#issuecomment-168327141
Probably can be closed then

In the upgraded Buildbot, I plan on enabling all platforms to build with C++11 by default soon, so whatever needs to be fixed for this to be fixed will be addressed at that point.

I don't really think that there si anything that needs "fixing", more a case of "supporting".
It seems the c++11 is simply not yet implemented in out adtools.
But anyway, thanks alot for taking a look

Looks like a broken toolchain. vsnprintf is part of C++11 (see: http://en.cppreference.com/w/cpp/io/c/vfprintf).
You might need to update your C library's development headers.
