--- 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.
