I did

./configure --enable-optimizations --enable-shared ax_cv_c_float_words_bigendian=yes

and it failed with the error messagesin the attached log.

The compiler is GCC 5.5.0 andconfigure set the C standard to C99, changing it to C11 in theMakefile did not help. Did i do something wrongly, or it just needs a later GCC?

Any help is much appreciated.
