There is a more general question: what is the oldest compiler which can
be used to build Emacs? IMHO it would be nice if `configure' will reject
"definitely old and unsuitable" compilers and issue a warnings like "your
compiler is likely too old and has not/has incomplete/has broken support
for feature X" in doubtful cases.
