That's strange.  Not only is the line number wrong, but also the file
name is corrupted.  A similar problem occurred in the other test case
failure on this platform.

Possibly this is related to the compiler bug that you mentioned in
another message.  Another possibility is a portability problem in
lib/quotearg.c, but I don't see offhand what it would be.

In scan-skel.l, suppose you replace this:

#define QPUTS(String) \
   fputs (quotearg_style (c_quoting_style, (String)), yyout);

with something like this:

#define QPUTS(String) \
   (fputc ("\"", yyout), \
    fputs (String, yyout), \
    fputc ("\"", yyout))

Does this work around the problem?  This is not a real fix; it's just
an attempt to see whether the problem is in quotearg.c, or in its
caller.
