strftime.c problem on dietlibc

[Eelco Dolstra]

Hi,

When compiling coreutils-5.3 with dietlibc I got the following compiler error:

In file included from fprintftime.c:7:
strftime.c: In function 'strftime_case_':
strftime.c:645: error: invalid use of undefined type 'struct __stdio_file'
strftime.c:737: error: invalid use of undefined type 'struct __stdio_file'
etc.

The problem is in the following line in the add(n, f) macro in strftime.c:

  p += FPRINTFTIME ? 0 : _n;

where p is a FILE *.  If the storage size of FILE is not known (which is the
case on dietlibc), then the compiler cannot increase the pointer p, not even by 
0.

Patch (against latest CVS) is attached.
