This is a telltale sign of a file name that includes non-ASCII
characters, and which Windows cannot translate into a corresponding
code in the DOS OEM codepage.  When a DOS program asks Windows to
produce a list of files in a directory, Windows replaces such
characters with underscores, and `ls' then cannot stat such a file
because there's no file named `__Muninstall'.

The bug (or rather a misfeature) is in Windows: it shouldn't allow
file names that have characters untranslatable into the DOS codepage.
Given that this is what happens, there's nothing a DJGPP program can
do to remedy it.  A workaround is to rename the file (using a Windows
utility such as Explorer or My Computer) to something that doesn't use
such non-ASCII characters.
