[PATCH] mbsstr, quotearg, xstrtol: pacify IRIX 6.5 cc

[Paul Eggert]

These were found when building the latest grep snapshot on IRIX 6.5.
* lib/mbsstr.c (knuth_morris_pratt_multibyte): Break "a=b=c;" into
"b=c; a=b;", since IRIX 6.5 cc complains about the former if b is
never used later.
* lib/quotearg.c (quoting_options_from_style):
* lib/xstrtol.c (__xstrtol):
Use enum instead of 0, to pacify IRIX 6.5 cc.
