ls-mntd-fs.m4 bug fix

[Jim Meyering]

coreutils' configure failed on HP-UX with hpcc.
The cause was here:

  configure:39945: checking for one-argument getmntent function
  configure:39988: cc -c -Ae -O  conftest.c >&5
  cc: "conftest.c", line 310: error 1649: Illegal integer-pointer combination 
for >.
  cc: "conftest.c", line 310: error 1563: Expression in if must be scalar.

I've made this change:

2006-09-24  Jim Meyering  <address@hidden>

        * ls-mntd-fs.m4 (gl_LIST_MOUNTED_FILE_SYSTEMS): Don't use '>' to
        compare a pointer against a literal "0".  That caused failures with
        at least HP-UX's hpcc.
