For instance, zlib contains some assembly routines for i586 and i686, but if I include those in an updated zlib package on sourceware 'latest' then the package won't work with older x86 processors. Does cygwin only officially work on i686, so that it is okay to use these routines and break compatibility with older systems? --Chuck
