Subject: Use CTYPE for isalpha in block-vvfat.c.
X-Git-Tag: xen-3.3.2-rc1~9
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=9bda8e3c102d5c6ffdec10fe92289dd0d7b7e5ab;p=qemu-xen-3.3-testing.git

Use CTYPE for isalpha in block-vvfat.c.

This call was missing the fix from:

  commit 5ed6aa6153110050c29bcd600a1424014cfbf1d4
  Author: Ian Jackson <iwj@mariner.uk.xensource.com>
  Date:   Wed Feb 20 16:30:05 2008 +0000

      Use new CTYPE macro for <ctype.h>

      This avoids passing a negative int to isfoobar,
      which is not allowed

Thanks to Christoph Egger for pointing it out (although we do not use
his proposed fix).
