No, that's not what anyone said. You can use the assembler on Cygwin to generate binaries that run on Cygwin (which is I think what you're looking for), but your assembly source code won't work as is -- you will need to make changes of the sort that DaveK and cgf state in the paragraphs above. stephan(); -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
