This was an unexpected surprise for me too.
Yes, bison, flex, and gperf are the three common tools for code generation.

I agree.
It could, in theory. But what should the Makefile rule do if 'gperf' was
not
found?
- If the iconv_open-aix.h file does not yet exist, it simply cannot
proceed.
(Except on AIX... - Should I make the dependencies platform dependent?)
- If the iconv_open-aix.h file exists but is older, what to do? Emit a
warning and compile the old .h file?
I don't fully understand all the issues here, but at the very least,
./configure could show a warning if gperf is not found or is too old.
