Greetings, Larry Hall (Cygwin)!

I can offer one idea of where this problem could originate from, which is in
no way pathological (i mean, in code, but comes from brain pathology of the
person introduced this problem into settings).
Windows PATH variable is constructed from two parts upon loading of user
profile.
First part is a system PATH in /proc/registry/HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/Session\ Manager/Environment/PATH
The other part is a user's PATH in /proc/registry/HKEY_CURRENT_USER/Environment/PATH
Both parts are, by no surprise, concatenated by semicolon.
Now, if some brain-dead programmer set an installation routine to append
"some\path;" to the end of either variable, you will get an empty element in
the path. Either "..;;..." or "...;".

So far, I'm not convinced that issue is Cygwin-specific. The fact that it
doesn't manifest in Windows is actually because of it's (windows) native
ignorance for this matter.
