* configure.in: added header checks for sys/param.h and sys/file.h.
* encryption.h: added typedef prototype for sum_func function
with the windows api to make microsoft compiler happy.
* sysincl.h: conditionally include sys/file.h and sys/param.h since
windows doesn't have them.
* Makefile.in:
- changed macros with ${...} to $(...) since nmake barfs on {}.
- added windows only make preamble
- split the all target into unix and windows branches
