[Bug libstdc++/61101] snprintf not part of std


http://gcc.gnu.org/bugzilla/show_bug.cgi?id=61101

--- Comment #7 from Paolo Carlini <paolo.carlini at oracle dot com> ---
I would suggest having a look to the config.log in the libstdc++-v3 build
directory and see which and how a C99 test is failing.

By the way (Jon) in mine I see a warning:

conftest.cpp: In function 'int main()':
conftest.cpp:54:23: warning: deprecated conversion from string constant to
'char*' [-Wwrite-strings]
 snprintf("12", 0, "%i");
                       ^
configure:16942: $? = 0
configure:16953: result: yes

which we should probably avoid.
