Different C/C++ indentation behavior on Win2000 and WinXP

[Ron Parker]

Hi.   I'm using the pre-compiled 21.3 for x386.   I was running on 
Win2000.   Recently, I got a new PC running XP.
I brought over the directory containing emacs, the _emacs file, and all 
of the .el files that were referenced.   It runs fine
except the indent level has changed from 4 spaces to 8.   This is 
driving me crazy as I work in a large body of code
that uses 4 space indents.   Nothing has changed except the OS.   I am 
not a LISP expert, but can follow instructions if anyone
has suggestions.

Thanks!
