windows compatibility changes

 * respect executable extensions
 * do not use weak symbols which appear to be broken on MinGW.
   Instead, the generated symbol constants contain constructor functions
   initializing the corresponding objects. Constructor priorities are used
   to ensure that the initialization takes place after the dummy (NULL)
   initialization.
 * do not change the working dir (causes trouble when sciteco gets passed
   relative paths but the exe is not in the current dir)
   instead look for teco.ini in program's directory
