win32 build process / bison

Could someonw please explain the syntax for external/customized build steps in MS VisualC++? I'd like to do make a change to three calls to bison to make the build process work if cygwin is not installed and the win32 native port of bison is used. Currently I change those calls manually from if not "X%CYGWIN%"=="X" bison --output=parsedate.c -v -d -S "%CYGWIN%\share\bison.simple" parsedate.y if "X%CYGWIN%"=="X" bison --output=parsedate.c -v -d -S "C:\Program Files\Cygnus\share\bison.simple" parsedate.y to bison --output=parsedate.c -v -d parsedate.y for instance. All (I think :) that needs to be done is to check if the environment variable bison_simple is set (and no other "rule" applies?) and make the call to bison. -- <?php $a=explode(" " ,"119 130 128 129 45 110 123 124 129 117 114 127 45 ". "125 117 125 45 117 110 112 120 114 127");for($i=0;$i<sizeof($a);$i++)print chr($a[$i]-13); // http://sb.phpOpenTracker.de | mail: sbergmann@php.net ?>
