This is how the string shows up in the .s:

[/home/john/src/cmsh/390]  more hlo.s
        .file   "hlo.c"
        .section        .rodata
.LC0:
        .string
"\310\226\246\204\250K@@\346\205\210\201\245\205@l\204@\201\231\207\244\224\205\225\243\242%"

The % sign now represents the newline in the ascii string.

The circumvention is to do a dry run with -Wall but without -fexec-charset, so
this is not a priority as far as I am concerned.
