According to Ralf Fassel on 8/5/2008 4:59 AM:
|     # call program: error: no such file /cygdrive/c/temp/foo.1234
|     # filename should be c:/temp/foo.1234
|     external_program "$TMPFILE"

Does it work to pass the contents of the file on stdin instead of the file
name as an argument?

external_program < "$TMPFILE"

|
| Alternatively, would it be a good idea to mark variables derived from
| auto-converted variables to become auto-converted on export, too?
| Something like the 'tainted' variables in perl?

Not really possible.  Cygwin has no idea how the environment was
populated.  Unlike 'tainted' variables in perl, where the variable is at
all times under the control of a single application, with env vars, the
management of environ is by cygwin1.dll but the specification of contents
of new variables is under control of the application.  There just isn't a
way to make all applications inform cygwin how those variables were created.
