Thanks for reporting that.  I installed the following patch
to try to fix it.  Please give it a try.

stdint: don't assume C++11 when compiling with g++
Problem reported for glibc 2.14 and g++ by Alexander V. Lukyanov in
* m4/stdint.m4 (gl_STDINT_H): Don't go to extra work to make it
work also in C++ before C++11, as that improperly inhibits
generating a substitute stdint.h for that case.
