Hi, I should have been clearer about the error I observed. I use xboard to interface my chess engine with FICS so I use the zippyPlay feature. Here's how to duplicate the error: [dand@dugovic xboard]$ autoconf -V autoconf (GNU Autoconf) 2.59 Written by David J. MacKenzie and Akim Demaille.

This seems to contradict the autoconf documentation which says: "If multiple AC_DEFINE statements are executed for the same variable name (not counting any parenthesized argument list), the last one wins." but my revised approach seems less error-prone and it works on my machine generating only: #define ZIPPY 1 and by default ./configure doesn't generate either statement and config.h contains: /* #undef ZIPPY */ The difference between #if and #ifdef is that although both check if the parameter is defined, #if also checks if the value of that parameter is non-zero. To me it seems simplest to only #define ZIPPY if we intend to use Zippy, and not care what the value of ZIPPY is as long as it's defined, so using #ifdef seems appropriate.
