Good point. I tried to verify that, so I did


[1a]
On a cygwin prompt
echo $PATH | grep -i msys

[1b]
On a msys prompt
echo $PATH | grep -i cyg


And got no conflicting results. (msys is not in the cygwin path, and cygwin
is not in the msys path).


[2]
'mount' only showed cygdrive on a cygwin prompt, and only msys on a msys
prompt


[3]
Looked for a 'msys' string in a random binary in the path:

[3a]
On a msys prompt:
strings `which ls.exe` | grep -i msys

gave me msys hits.


[3b]
on a cygwin prompt:
strings `which ls.exe` | grep -i msys

gave me no hits.


So it at least appears to me that the environments are not conflicting for
me personally. Of course, that could very well be the case for the error
results of the original poster.

PS:
if anyone knows of better tests/checks to see if the environments are
intermingled in some way, I'd love to hear it.
