Umm.  The FULL.EXE is b20.1.

I'm not sure exactly what you've accomplished but to replace a file on Win32
you must not have the file open.  Therefore, you can't use Cygwin to replace
the cygwin1.dll.

And combine the two and the glass is even darker.

What instructions are you reading?  Perhaps the instructions are old and need
rewritten.

See my webpage for some newbie help, URL posted in the .sig.

Only if you're a Cygwin developer.  Which is needed if you want to help.

Typically, at least for well constructed projects, all that is required to
rebuild is `./configure' and `make'.

Please do read my webpages.  And to answer your question on paging, `diff
--help | less' will page the output for you.  BTW, it would help to understand
UNIX before using Cygwin; but, it is possible to learn Cygwin without knowing
UNIX.
