This may have something to do with the change in extern inline
behaviour.  There is a fixincludes patch which should have cleaned up
the header files.  Search for glibc_c99_inline in
fixincludes/inclhack.def.

Don't run ./configure.  Always run configure in an empty
directory--i.e., SRCDIR/configure.  This is documented in the
installation instructions.  You should first see if that fixes your
problem.
