Well, that is the way it works now. In the snapshots and the next release B21
epath will map to /cygpath/e/temp just to give you a heads up.
This has to do with the mapping and remapping of the filesystem paths.

Only if somefunc.exe is a non-cygwin program. cygwin built program a cygwin

Suggestion: create your own pwd so that it always returns the the full win32
path. See the cygwin api docmentation.
