lynx-dev Getting DIRED_SUPPORT to work with MingW32/Windows

[vtailor]

I sent a recent message on this topic, but it apparently didn't get
posted.  If you define DIRED_SUPPORT for the MingW32 compile of the
February lynx.exe, and do some minor additions for LYLocal.c so that
uid_t is known, you get a working lynx.exe with a dired menu when you
press the 'f' key in a local directory.

However, if you attempt to do a dired "remove file" for

        file://localhost/c:/tools/gnu/lynx/ABOUT-NLS

you get an error message of the form:

        Unable to get status of '/c:\tools\gnu\lynx\ABOUT-NLS'.

I tried changing HTDos.c so that any initial '/' in a path is deleted,
but that doesn't seem to make any difference.
