Known issue (see README.linux).

Ok, but can we be sure that all the sys/io.h and asm/io.h files use
the same __GNUC__ test? What I mean is: are we sure that there isn't a
platform where sys/io.h or asm/io.h exists and works with non-gcc
compilers? So we would deactivate access that worked until now?
