[Message part 1 (text/plain, inline)]

I have used the Sysinternals process explorer, 
(http://technet.microsoft.com/en-us/sysinternals/bb896653), to determine 
the loaded dlls. Unfortunately it does not show a dynamic dependency 
tree. This shows that when a file is visited, the distribution version 
of emacs 24.4 loads zlib1.dll from the MinGW installation and 
libgcc_s_dw2-1.dll also from the MinGW installation. These are the only 
non-microsoft dlls I can see. The version of emacs 24.4 I built does not 
load any non-microsoft dlls. I have attached four text files showing the 
dlls loaded by the distribution version of emacs 24.4 when no files have 
been visited, the dlls loaded by the distribution version after a file 
has been visited, the dlls loaded by the locally built version of emacs 
24.4 when no files have been visited, and the dlls loaded by the locally 
built version of emacs 24.4 after a file have been visited.

Hope this helps.

Regards
Bill Farmer
