Are the tests really stumbling in that case?
If 'lex' generates .c files that don't work
unless one #defines a magic symbol, then arguably
'lex' isn't working.
Perhaps a better fix would be for 'configure'
to #define YY_NO_UNISTD_H as needed, and
to leave contest.l alone? That way, the fix
would be visible to C programs that are being
compiled.
