Using gcc 4.4.5 I get *tons* of warnings from gnulib headers: Eg: In file included from ./SOURCE/src/libpspp/argv-parser.c:26: ./SOURCE/gl/xalloc.h:176: error: no previous prototype for 'x2nrealloc'
Apparently this doesn't happen on gcc 4.7.2
The following patch fixes the problem for me. I don't know if the conditionals
are correct for other compiler versions.
