Many of the numeric limits specified in the standard are, I think,
intended to discourage setting any fixed limits at all. The easiest
way to meet the requirement for 31 significant initial characters
is not to impose a fixed limit. Even for linkers that impose a
fixed limit, the C standard's requirement encourages implementers
to make the limit no less than 31 characters, just to make the
compiler's job easier.
I infer from your failure to answer my question that you don't know
of any such linkers (you could have said so several responses ago).
But that's ok; Robert Wessel has cited an example (the linker for
zVSE, an IBM mainframe OS, which only supports 8-character names).
Even there, the workaround is to use an automated tool on the
object files to map long names to shortened encoded names, not,
as you suggested, to force the programmer to invent such names.
