bad passphrase error passing it into GPG on Windows 98 using stdin

Right.  Well, this kind of question comes up so often that
it really needs to be approached by Werner.  You should
be able to pass a handle to a pipe to the Ming/W32 gpg
the same way that you do to gpg on Linux, without doing
a conversion with osf_filehandle().

But I may just put a program up here on the list that will
help with that.  Perhaps a tiny program in C that takes
a command line argument of a file descriptor and returns
an "osf_filehandle ( )" converted to a string at it's stdout.
Then a script could redirect the output to a variable.
It would be worth the effort just to be able to stop
answering these same questions over and over again.
