// All XASH_* macros set by this header are guaranteed to have positive value otherwise not defined

// You can generate #undef list below with this oneliner:
//   $ cat build.h | sed 's/\t//g' | grep '^#define XASH' | awk '{ print $2 }' | sort | uniq | awk '{ print "#undef " $1 }'
// 
// So in various buildscripts you can grep for ^#undef XASH and select only second word
// or in another oneliner:
//   $ cat build.h | grep '^#undef XASH' | awk '{ print $2 }'
