New description:

 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); }
                                                 ^
 }}}
