It seems that the C code uses $! as an (ill-advised) way to communicate "constant not found" to the caller, instead of die-ing right from the C code. The C code seems to set $! to ENOENT, so the most consistent way to handle that from the Perl code would be to check $! for ENOENT instead of trying to do string matching:

... manually coded string lookup table ...
not_there:
    errno = ENOENT;
    return 0;
}

I would look towards POSIX to get at the value of ENOENT for your OS, and then use that for the comparison.
