I'd need to see your entire script to know for sure.  Perhaps you are
using calls to 'set' or using shell functions, either of which modifies
$1 from the value that you passed on the command line.  But the point
remains - your improper quoting of $1 is not a cygwin-specific issue.

Less likely.  But without seeing your entire script, it's hard to say.
You haven't given anyone else enough to go on.
