Consider using the m4sugar namespace. We have threatened to add warnings
when using the raw m4 namespace from within configure scripts, because it
is too easy to run into conflicts. For that matter, why not use
m4_toupper and m4_tolower, instead of rewriting them yourself? Not to
mention that those macros are more robust to arguments that include
potential macro names (your version is underquoted, and would end up
expanding such a macro).
