bug#8295: coreutils 8.10 portability fixes

[Andreas Stolcke]

Two sets of fixes:

- Several places where iterator variables are declared inside for(), failing 
compiles
   on systems that support c99.

- The inclusion of <langinfo.h> has to be protected by 
        #if HAVE_NL_LANGINFO
  instead of 
        #if HAVE_LANGINFO_CODESET
  to match the piece of code later where the langinfo is actually used.

These problems surfaced when building on an old IRIX5.3 system with gcc 3.4.6.
