fts.c doesn't compile with C89 compiler

[Bruno Haible]

Hi,

Compiling coreutils-6.4 with gcc-4.1 and

./configure --prefix=/packages/gnu \
  CPPFLAGS="-Wall -Wformat=2 -Wmissing-field-initializers 
-Wmissing-format-attribute -Wpointer-arith -Wstrict-aliasing=2 -Wwrite-strings" 
\
  CFLAGS="-O2 -g -Wbad-function-cast -Wdeclaration-after-statement"

yields a warning:

fts.c:1076: warning: ISO C90 forbids mixed declarations and code

gnulib still assumes C89 only. Here is a fix.

Jim, OK to apply?

        * fts.c (fts_build): Move variable declaration, for C89 compliance.
