ccgnu2.dll and ccext2.dll mingw32 makefile and related patches

[Federico Montesino Pouzols]

     Hi, I have modified Makefile.gcc so that two separated dll's are
built with mingw32 as in posix systems. It is attached.

     When modifying the makefile I have tried to include all the
source files that are used in the Makefile.am of the posix tree, what
has made me to find the following things:

     - Adding process.cpp required an small patch which is attached.

     - dir.cpp and dso.cpp: the Win32 code corresponding to these unix
       sources seems to be in the Win32 specific file `file.cpp', so
       they have not been added. There are also three files:
       friends.cpp, events.cpp and file.cpp in the Win32 directory
       that contain the Win32 port of the corresponding posix files.

     The last point shows that the Win32 and the posix source trees
are not completely merged. However it seems there is only a little
work left to completely merge the two trees. Are these trees still
separated for any reason? If they are not and there is no one currently
working on it, I would be glad to finish the merge.
