The bug, IMHO, is in the use of getopt, that departs from POSIX'
specifications for the function, thus requiring to compile your own version
of it, which is a patently bad style.

I wonder, how GNU's getopt implementation, where flags' arguments can be
optional, deals with the cases of such an option followed by something, that
begins with a dash itself:
m4 -d -X
Is "-X" an argument for -d, or a separate flag?
-mi
