So is flex a requirement to build Sage? If it is, then I'll add to the

For what it's worth, Sage / Singular builds on Cygwin where "flex"
does not seem to be installed.

Thanks mike.

Another thing which needs to be added to prereq (at least on Cygwin) is "file".

I'm really surprised that 'file' does not exist on Cygwin. It is required as part of POSIX

http://www.opengroup.org/onlinepubs/9699919799/utilities/file.html

and IMHO is a pretty common and useful command. Something like 'lex' and 'yacc' I can see are less useful to most people, but I would have thought having 'file' installed was almost as useful as 'ls'!
