There's nothing wrong with -std=gnu++98.  The problem is with configure
testing C99 macros with -std=c++98, which makes no sense and only works
on glibc because they use -D_GNU_SOURCE indiscriminately with g++.  Fix
those configure tests to use -std=c++11, as we did on Cygwin, and the
features should be enabled.

The attached patches for GCC enable _GLIBCXX_USE_C99 support with thecurrent feature test macros.
