Perhaps if you ran this command:
gcc -E -O3 -D_GNU_SOURCE lib/argp-fmtstream.c
and looked at the output you might see what the __extension__ problem

One thought is that some system file has #define'ed mempcpy before
mempcpy.h was included, to a set of tokens that includes __extension__.
Does it fix things if you insert this line at the start of mempcpy.h:
and append this line to the end of that file?
