Is that compliant with the C standard?

Instead of:
#ifdef isalpha
#error
#else
...
make a bunch of:
#undef isalpha
#undef isdigit
...
It would be good to have #undefs in one "#ifdef compiler_or_OS_version",
because in general it's possible that isalpha() defined by the compilation
environment doesn't have anything to do with isalpha() defined by the C
language, so in that case throwing #error is the right thing to do.
