Steps:

1. Download MinGW from http://www.mingw.org

2. Put C:\opt\MinWG\bin in the path before C:\opt\cygwin\bin

3. Open a windows cmd shell

4. Make sure subversion is installed, and check out the repository

{{{
svn co svn+ssh://hannah@contact.mpi-sb.mpg.de/KM/ir/SVN/autocompletion
}}}

5. Now compilation of the main program 

{{{
make startCompletionServer
}}}

will give many errors!! E.g.: MinGW does not support pthreads, no fseeko / ftello, missing regex.h, ...

7. Download the following files (header files + lib) from ftp://sourceware.org/pub/pthreads-win32/dll-latest

{{{
pthread.h
sched.h
semaphore.h
libpthreadGCE2.a  (the E stands for exception)
}}}

8. Add the following redefinitions to the g++ options + the path where to find the above header files

{{{
-Dfeeko=fseek -Dftello=ftell -Duseconds_t=size_t -I.
}}}

9. Change the socket includes in CompletionServer.h to

{{{
#ifdef __MINGW32__
#include <winsock.h>
#else
#include <netinet/in.h> /* for sockets */
#include <arpa/inet.h>
#endif
}}}
